I read “Molecular Biology of the Cell” when dabbling in bioinformatics (one of the books mentioned in the article).

It’s an excellent textbook. You’ll need a base level of chemistry and biology - not two of my best subjects, But despite that I still got a lot of it.

jkimmelonOct 21, 2015

Molecular Biology of the Cell (Alberts) is free through NCBI!
Many investigators jokingly refer to it as 'the bible'.

I can definitely recommend "Molecular Biology of the Cell", which is a undergrad-level textbook about cells. The latest edition is always very expensive, but you can get older versions cheaply. Link: https://www.amazon.co.uk/gp/product/0815341067

sansnommeonJan 6, 2020

Sorry I meant Molecular Biology of the Cell. I think it's meant as a reference more than anything else. Bio is like ML in that it moves very quickly, so there is the need for constantly updated evergreen texts.

DavidSJonApr 5, 2020

Reading: The General Theory of Employment, Interest, and Money by Keynes.

Studying: The Molecular Biology of the Cell by Alberts et al and Advanced Macroeconomics by Romer.

RivieraKidonApr 2, 2020

Part I of Molecular Biology of the Cell is the best read in my opinion, regardless whether you have a CS background.

bluejellybeanonApr 12, 2018

For further reading, I would highly recommend 'Molecular Biology of the Cell'

https://www.amazon.com/Molecular-Biology-of-the-Cell/dp/0815...

thronemonkeyonAug 8, 2012

The best textbooks for this (this is something of a consensus in the field also) are Molecular Biology of the Cell by Alberts et al. and Lehninger Principles of Biochemistry by Nelson and Cox.

bbgmonJune 14, 2009

It's hard, especially at the molecular level where our knowledge is changing on a near daily basis. I have spent years in the world of structural biology, but know only a little about cell biology.

Having said that, Molecular Biology of the Cell (referred elsewhere) is a great book.

rwmjonJune 20, 2017

I can also recommend an undergrad text book called "The Molecular Biology of the Cell". New editions are expensive, but second hand or older editions can be had relatively cheaply.

Molecular Biology of the Cell[1] is a typical recommendation.

teekertonFeb 21, 2015

As a biologist I'd put "Molecular Biology of the Cell" on the list (http://www.ncbi.nlm.nih.gov/books/NBK21054/). This book was basically my M.Sc. exam in molecular biology. It is very rich in helpful illustrations. I'd think even someone with enough interest but no background in biology can extract a lot of information from it.

vaylianonJuly 27, 2019

Given the considerable size of the books in question I think it is actually good that they do not cover absolutely everything up to the latest research. I have read large fractions of these books but I never fully read any of them. There is simply too much to learn.

It's much better if you read the relevant parts of these books and then ramp up from there with the papers that are actually relevant to your studies/work.

With that being said, the Molecular Biology of the Cell and the Biology of Cancer are also very enjoyable (but challenging) reads just for satisfying your curiousity. But don't expect to finish these within a 3 months.

fadysonAug 10, 2018

Read Molecular Biology of the Cell. It's an indispensable book for anyone studying or interested in cell biology and molecular genetics. It has been described as “the most influential cell biology textbook of its time.”

When I started out in a systems biology lab with a physics and CS background but no biology, they gave me this book:

Molecular Biology of the Cell
http://www.amazon.com/Molecular-Biology-Cell-Alberts-Al/dp/0...

The description of the DNA --> RNA --> protein pipeline was really satisfying to someone with my background, full of codes, error-correction algorithms, and rate-limiting steps. I think of it as the Numerical Recipes of biology.

Theses are the main two books in the field of molecular biology. If you want to go more specific, let me know.

nextosonDec 21, 2013

I'm quite fond of Watson's Molecular Biology of the Gene (not to be confused with Molecular Biology of the Cell).

In the stats camp, Jaynes is fantastic, alas a bit difficult. But the prerequisites are very modest. It's self-contained.

Hoel, Port & Stone's volume is a great introduction to basic (w/o measure theory) probability.

RivieraKidonAug 21, 2017

Even in this day and age, you can become a "quasi-polymath" if you like learning and are efficient at it. By that I mean, reach 80% understanding of a lot of fields with 20% the effort of becoming an expert. You can do that by choosing good learning resources and focusing on conceptual understanding and fundamentals.

This is something I wish to do over time, learn about a bunch of fields to, say, about undergraduate level. Right now I'm reading Molecular biology of the Cell (best textbook I've ever come across by the way) and it's rewarding to be able to understand much more of biology research news for example. And when you want to learn about some specific sub-topic on Wikipedia, you have the fundamentals to do that without saying "I know some of these words".

mindcrimeonAug 7, 2012

One of the guys at SplatSpace[1] who is something of an expert on genetics / biology / biohacking stuff is always recommending people read this book:

Molecular Biology of the Cell

http://www.amazon.com/dp/0815341059/?tag=hyprod-20&hvadi...

It's not on synthetic biology, mind you, but presumably some understanding of the natural biology is a prerequisite to doing the synthetic stuff. Anyway, he works for GSK doing some pretty interesting stuff and is an all around smart guy, so I tend to assume his recommendation is a good one. YMMV.

mjg59onMay 25, 2020

Molecular Biology of the Cell is a wonderful book (my first PhD advisor was one of the authors of the 3rd edition), but if you're more interested in the purely genetics side of things then I'd recommend Genes by Lewin - it's definitely the book I relied on most during my undergrad degree, and it's written in a way that largely lets you bootstrap from not having a strong biology background.

ejstrongeonMay 13, 2016

You can access a recent copy of Molecular Biology of the Cell through the US National Center for Biotechnology Information:

dekhnonJan 16, 2019

if I want to convince somebody of something scientific, I point them at a textbook written by an authority (say, Bruce Alberts, who wrote Molecular Biology of the Cell). For each fact in the book, it contains citations to the original scientific publications (most of whom were written by authorities, but some simply by experts).

Probabilistically, it seems like authorities are the least likely to be wrong.

dirtyauraonFeb 9, 2012

> His biology stuff, for instance, is decidedly worse than the mathematics.

I dunno.

I've been studying cell biology on my spare time. I've been using The Molecular Biology of the Cell (http://www.amazon.com/Molecular-Biology-Cell-Bruce-Alberts/d...) that in my opinion is a great book, and as far as I know, is well-respected in general.

Still, watching Sal's biology videos has been of great help. Although I think e.g. his organic chemistry videos are better executed (~10 minutes per video, a bit less packed, better splits by content), I still think that his biology videos are a super-valuable resource. I've been watching some MIT lectures too, but visualizations, which are necessary for biology, aren't properly visible in them. Of the free biology content in the web, Sal's videos are the best IMO.

noam87onMay 6, 2017

um some parts are more high-level than others, but a lot would be gibberish. Familiarity with the contents of e.g "Molecular Biology Of The Cell" would greatly increase your experience. -- That book is big and exhaustive (and expensive), a focused intro to the same material is MIT "Introduction To Biology" on EDx! It's an amazing course!

The book and MIT course also give a good enough conceptual intro to the chemistry concepts you need too. Obviously the rabbit hole goes deeep tho... people spend lifetimes scratching the surface.

Molecular Biology Made Simple and Fun

Do not let its silly title fool you. This is an excellent book containing real biology facts. Plus, unlike Molecular Biology of the Cell, if this book falls on you from a high shelf you have a chance to survive.

Of course, the book predates siRNA. Nothing ages faster than a molecular biology book.

dekhnonJuly 26, 2019

Biology of Cancer ed 2 is from 2013 and nothing has changed tremendously to the point where the book would be out of date.

Molecular Biology of the Cell ed 6 is from 2014

Molecular Biology fo the Gene is a bit older and I would generally not recommend people read it, but the problem is (IMHO) the alternative, Genetics by Lewin, is genetics-oriented instead of molecular biology, and I find that most CS folks understand MB and find genetics confusing.

Review articles are good, but I still recommend starting with textbooks before moving on to reviews.

atakan_gurkanonJune 12, 2011

Did you consider learning biology?

You sound smart and comfortable with solving problems with a computer, yet you do not seem to be satisfied with developing applications for people to use in everyday life. Perhaps your calling is to develop computer programs to solve scientific problems. I am extrapolating from my experience here. I am an astrophysicist and do simulations for studying problems in stellar dynamics. It is really fun, but sometimes I wish I had the background in biology to have the option to switch to that field, since there seems to be tons of interesting problems and really smart guys there; in particular in molecular biology and in brain research. I think if I knew what I know now when I finished high school I would go for biology and not physics (this does not mean I regret my choice though, I do not), or at least take a few biology courses.

Unfortunately I cannot recommend many books. The only decent biology book I have is "The Molecular Biology of the Cell" by Alberts et al. It is really good. I have the feeling others here can make better/more recommendations if you ask. This is not necessarily an engaging book.

Good luck!

hyperion2010onOct 15, 2016

Not directly related to medicine, but I advise every high schooler and undergrad that I mentor to take as much math and/or computer science as they can if they are interested in biology or neuroscience (or to major in physics). There are not going to be PhD level jobs given out for graduate work that was essentially being a lab tech for 6 years, no matter how much cheap labor current professors need/want. That said, I also tell them that if they want to be successful they need to read and understand most of Molecular Biology of the Cell because it is the foundation for understanding the fundamental parts of biological systems.

gbergeronJune 22, 2016

From [1], "Mycoplasma genitalium: it has only about 480 genes in its genome of 580 070 nucleotide pairs." So in average, each gene is 1200 nucleotide pairs.

A nucleotide is one of [A,T,C,G]. So that means it encodes 2 bits of information.

473 * 1200 * 2 = 1 135 200 bits, or 141.9 kilobyte.

Of course, this is coming from a software developer using numbers from Google, so I might be wildly wrong.

[1] "Molecular biology of the cell" by Bruce Alberts

hyperion2010onAug 26, 2015

I'm exaggerating a bit but mostly because my experience is that the kinds of questions that are asked on tests a lower levels of science education are things that you simply know at higher levels and not because you were tested on them but because you have to use them and apply them every day. Better to have courses that expect you to have read all of Molecular Biology of the Cell in advance and present material with that expectation. That way students can see the real applications of the knowledge that we build on and not just see it as some stupid thing to be memorized for the next certificate. I get no prize for knowing IUPAC nomenclature, but I couldn't even start to do my work without it. The expectation should be as such, you get a prize for thinking creatively about how one could answer questions or for coming up with answerable questions that haven't been asked before.

I actually think that formal courses are an excellent way to learn 'textbook' material, but they are far more useful when you know you are going to use that knowledge in the future. The question for me is whether, at the highest levels, we should be focusing our courses, and rewarding people for the equivalent of learning how to walk when we need them to fly.

I've always heard Alberts' Molecular Biology of the Cell touted as the "bible of low-level bio", can you weigh in on that?

ahubertonDec 27, 2020

So .. it is not easy to get into this field. From the outside we tend to see DNA as some freestanding thing that fascinates us. The biology people intertwine DNA with everything they do. The route to knowing about this stuff therefore goes via learning about biology first. One of my favorite books, Molecular Biology of the Cell, covers DNA thoroughly.. by spending time on it on almost every of its 1300 pages. But it is all in between "the rest of biology". In a way I can understand this of course, but it is very very hard work.

LargoLasskhyfvonSep 30, 2020

Around the year 2000+/-2 that was my daily experience on the track from Hagen in Westfalen(near Dortmund) to Cologne or Düsseldorf. When it went over the Autobahn there was always gridlock. I noticed that mostly out of the corners of my eyes, while reading Tipler's Physics, Stryer's Biochemistry, Albert's Molecular Biology of the Cell, or other sciency stuff like that, comfortably munching something and sipping coffee. Hopping into some bus, tram, subway for another 10 to 20 minutes, arriving relaxed and fit.

kensonFeb 13, 2015

You can find this authoritative ignorance of unknowns in more recent writings too. It's interesting to read a pre-1960s geology book - before continental drift was proven - and see how they explain continent formation. They'll often present some totally wrong theory without any trace of doubt. Another example is pre-1960s biology books that talk about DNA and give it a bogus role.

To be clear, I'm not criticizing these books for not having the answers, or even for being wrong. It's being confidently, authoritatively wrong that is concerning. It also makes me wonder how much of what we read now is also authoritatively wrong. (I have my suspicious about cosmology.) A counterexample is the book "Molecular Biology of the Cell", which is good about explicitly pointing out what is unknown rather than papering over it.

kolinkoonFeb 3, 2018

As a software engineer who decided to learn about biotech with absolutely no background, here is how I started:

- Organic Chemistry course on itunes U (don't remember which one, just first 4-5 lessons)

- Introduction to Genetics: A Molecular Approach by Terry Brown

- Virology course on iTunes U, by Vincent Racaniello - https://itunes.apple.com/us/podcast/w3310-virology-videocast...

- Molecular biology of the cell book ( https://www.amazon.com/Molecular-Biology-Cell-Bruce-Alberts/... )

After going through that (took ~3 months full time), I went for a month to the Bay Area, went to Biocurious hackerspace, to get some practical experience, and within a month I did stuff like ordering custom dna online, and putting it into bacteria :)

All the above was sufficient to understand basics of whatever I'm reading now about biotech, and gain extra knowledge when necessary.

Some notes:
- Virology may seem a weird addition, but the course by Racaniello is super-fun, and if you understand how viruses work, you will understand how everything else works
- If, like me, you were afraid of Chemistry and Biology in high school, don't worry. Organic Chemistry deals just with just four basic elements, and Molecular Biology is really not much different from mechanics - not that much to remember, and a lot to understand.
- Even if you complete just 3-4 first chapters of all the above, you will get nice foundations for understanding biotech.
- There are bio hackerspaces in major cities in US (not so much in EU - regulations)

Well, if you want to get a clue about how molecular biologists think you could do a lot worse then read "The eighth day of creation." It's a general history of molecular biology. If you find any of it confusing then a good introductory text book may help; Molecular Biology of the Cell or Stryer would get you started (and will be available in any decent college library).

As for the protein folding or the protein function question google around computational chemistry, but be warned -- this is tough stuff! But if you are shit hot, please come as we need the help...

"Does the machinery in the cell just randomly bind to plasmids and do what they say?"

Sort of. Please read Molecular Biology of the Cell, Molecular Biology of the Gene, and Biochemistry. It's explained in detail (what people have observed). TL;DR: yeah, machinery in the cell binds to plasmids. No, it's not random- it's a highly biased process.

dekhnonApr 24, 2014

Yes I have read it. PS: I'm a scientist and studyng cancer is part of what I do. Please read "Molecular Biology of the Cell".

yes, we're learning a lot, but no, the promised revolutions aren't forthcoming. Not only are there technical reasons why it's unlikely we'll see a very near term revolution in treatment. There are huge political, monetary and bureaucratic reasons, too. They are just as important to understand as the technical reasons.

If you had most of these things I think you would have a good shot at a compbio position:

- statistics, probability, and especially probabilistic inference

- nix/gnutools

- multiple scripting languages (Ruby, Python, Perl, BASH)

- at least one data-oriented language (R, Octave)

- understanding of molecular biology (read Molecular Biology of the Cell)

- applying machine learning tools to new problems

- understanding the major high throughput biological technologies and the kinds of data they produce, along with the current tools used for processing the data

You could pick up all of that in a year of intense self-study, and less assuming you already have some of those skills.

mechanical_fishonDec 19, 2008

What I find amusing is the phrase "nothing more than electrical signals". As if electrical signals were somehow trivial to understand. As if one individual neuron didn't embody so much chemistry and physics and history (it's got your entire genome stored inside!) and complex behaviors (it's a tiny little creature!) that we can't even understand it in isolation.

I'm not sure whether to recommend Dennett's Consciousness Explained or to compel the questioner to work through The Molecular Biology of the Cell, followed by (e.g.) Hölldobler and Wilson's Journey to the Ants -- and then keep going -- before trying to dismiss the complexity of a network of neurons with the wave of one hand.

IAmEveryoneonApr 27, 2020

I studied bioinformatics and found the standard textbook, Albert's "Molecular Biology of the Cell"[0] to be one of the most captivating books I've read. It's like those extremely detailed owners' manuals for early computers, except for cells.

The amount of complexity is just absolutely insane. My favourite example: DNA is read in triplets. So, for example, "CAG" adds one Glutamine to the protein it's building[1].

There are bacteria that have optimised their DNA in such a way that you can start at a one-letter offset, and it encodes a second, completely different, but still functional protein.

I found the single cell to be the most interesting subject. But of course it's a wild ride from top to bottom. The distance from brain to leg is too long, for example, to accurately control motion from "central command". That's why you have rhythm generators in your spine that are modulated from up high (and also by feedback).

Every human sensory organ activates logarithmically: Your eye works with sunlight (half a billion photons/sec) but can detect a single photon. If you manage to build a light sensor with those specs, you'll get a Nobel Prize and probably half of Apple...

If you just want to read, there are a few books that are detailed, but still accessible. Any one would give you a much better understanding of what's possible:

* Human Molecular Genetics by Strachan and Read -- this is a tome, but it's a great introductory reference to the field. (A lot of first-year grad students read this book when coming to molecular genetics from engineering and CS, incidentally.)

* Molecular Biology of the Cell, by Alberts et al. -- an even bigger tome, but one you'll find on every researcher's bookshelf.

* Genes NN by Lewin (where NN is an ever-increasing roman numeral; you can estimate the amount of time someone has been in the field by the size of the roman numeral on their copy) -- this is more of an undergraduate introduction to molecular genetics. The other books (especially MBC) are more useful as references, but this book is fairly accessible to newcomers.

* Recombinant DNA by Watson et al. -- I hesitate to include this in the list, because it's now sadly outdated (written in 1992), but I still think it's one of the best-written, most accessible introductions to things like transgenics, genetic engineering, etc. Describes everything in a friendly, Scientific American style. It's also small. If you want a quick, friendly introduction to what was state-of-the-art 15 years ago, this is a great book.

I know that most of these books are kind of thick, and that you said you didn't want to digest the whole curriculum, but I don't tend to read pop-science books in this field. I don't have much of an opinion on any particular popularization of molecular genetics. But if you want to gain a real understanding of molecular biology, these are the books you'd most likely be told to buy for molecular genetics 101 at your local university.

PS: the giant metal birds eat Acme brand exploding bird seed, naturally....

Adam_OonAug 8, 2015

Maybe you are right, it is not in the same category as The Selfish Gene. However, I thought the parts about the early history of computing were written very well, as someone who did not know much about it before.

I was also thinking that a non-fiction book with no fluff and no injection of personality/flair from the author is a textbook. There are many outstanding textbooks (like Molecular Biology of the Cell) which offer pure information, but I think commercial non-fiction books are aimed at a more general audience. The author needs to fluff a book up a bit to make the material approachable. I also wonder how some non-fiction books would read if untouched by editors.

skosurionDec 12, 2013

Depends on what level. Wikipedia is actually quite good for this sort of thing. The classic book as a basic overview of molecular biology in general is the Molecular Biology of the Cell [1]. A really cool website to look at on cutting edge studies such as these is the ENCODE consortium's publications in Nature [2]. They simultaneously published 30 papers last year, and this is a really cool meta page that explains the ENCODE project and what they found.

Epigenetics is a very interesting area, and I expect it to increase in importance following the ENCODE project that just came out.

The NYTimes article is a bit strange, though, trying to politicize epigenetics through the "mommy wars". The article also muddles the difference between genetic issues due to aging fathers and epigenetic issues. The recent Icelandic study links mutations in sperm from aging fathers to autism and schizophrenia, which is genetic (the mutations show up in genome sequencing), so it's basically irrelevant to the article's epigenetic thesis. The NYTimes article mentions a theory that maybe epigenetic regulation is reducing DNA repair and causing mutations, but that's a pretty tenuous connection.

It's silly to turn this into a "blame game", but it is interesting that males and females contribute different types of genetic errors: females typically introduce chromosome errors, while males introduce DNA mutations. 20% of human eggs have the wrong number of chromosomes, compared with 3-4% of sperm. A cell has to split the chromosomes twice in meiosis to form a gamete, which is a difficult process where a lot can go wrong. Eggs sit around potentially for decades and then need to twice split properly, and this becomes much more error-prone with age. The first split happens at ovulation, and the second at fertilization (which is much later than I'd expect). These errors in chromosome separation are the leading cause of miscarriage and mental retardation. On the other hand, males are the main source of DNA mutations, since sperm are constantly being created, and each round of DNA replication has a chance to introduce errors. [Reference: Molecular Biology of the Cell, chapter 21, which is an interesting book]

Last week I read the book "The Epigenetics Revolution", which I recommend as it gives a good description of epigenetics. http://www.amazon.com/The-Epigenetics-Revolution-Understandi... (non-affiliate link)

If you like this book you will probably also like the gold standard for cellular biology: Molecular Biology of the Cell (http://www.amazon.com/Molecular-Biology-Cell-5th-Edition/dp/...).

It costs more but it's worth it. It's a deeply informative book that covers a large spectrum of topics that you can read without much background knowledge in biology. It's the same book your doctor or bioinformatics professional probably used in school learning about cellular biology.
