Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.

You’re nothing but a pack of neurons.
FRANCIS CRICK -
It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.
FRANCIS CRICK -
It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.
FRANCIS CRICK -
Avoid the temptation to work so hard that there is no time left for serious thinking.
FRANCIS CRICK -
One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.

We are sometimes asked what the result would be if we put four +’s in one gene. To answer this my colleagues have recently put together not merely four but six +’s.

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.
FRANCIS CRICK -
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.
FRANCIS CRICK -
If the code does indeed have some logical foundation then it is legitimate to consider all the evidence, both good and bad, in any attempt to deduce it.
FRANCIS CRICK -
Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.
