Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.

Image
The balance of evidence both from the cell-free system and from the study of mutation, suggests that this does not occur at random, and that triplets coding the same amino acid may well be rather similar.
Francis Crick
Image
If, for example, all the codons are triplets, then in addition to the correct reading of the message, there are two incorrect readings which we shall obtain if we do not start the grouping into sets of three at the right place.
Francis Crick
Image
A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.

Evolution is cleverer than you are.
Francis Crick
Image
A theory should not attempt to explain all the facts, because some of the facts are wrong
Francis Crick
Image
In the fullness of time, educated people will believe there is no soul independent of the body, and hence no life after death.
Francis Crick
Image
It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.
Francis Crick
Image
Jim and I hit it off immediately, partly because our interests were astonishingly similar and partly, I suspect, because a certain youthful arrogance, a ruthlessness, an impatience with sloppy thinking can naturally to both of us.
Francis Crick
Image
Christianity may be OK between consenting adults in private but should not be taught to young children.
Francis Crick
Image
Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid.
Francis Crick
Image
When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There's something that might be called the 'graduate student syndrome' graduate students hardly believe they can make a discovery.
Francis Crick
Image
A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
Francis Crick
Image
There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.
Francis Crick
Image
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
Francis Crick
Image
I also suspect that many workers in this field [molecular biology] and related fields have been strongly motivated by the desire, rarely actually expressed, to refute vitalism.

You’re nothing but a pack of neurons.
Francis Crick
Image
It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.
Francis Crick
Image
If poly A is added to poly U, to form a double or triple helix, the combination is inactive.
Francis Crick
Image
It is one of the more striking generalizations of biochemistry - which surprisingly is hardly ever mentioned in the biochemical textbooks - that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature.

A busy life is a wasted life.
