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 -
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.
FRANCIS CRICK -
If revealed religions have revealed anything it is that they are usually wrong.
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 -
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.

Exact knowledge is the enemy of vitalism.
FRANCIS CRICK -
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 -
A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.
FRANCIS CRICK -
Rather than believe that Watson and Crick made the DNA structure, I would rather stress that the structure made Watson and Crick.
FRANCIS CRICK -
The dangerous man is the one who has only one idea, because then he’ll fight and die for it.

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.

An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.
FRANCIS CRICK -
Again the message to experimentalists is: Be sensible but don’t be impressed too much by negative arguments. If at all possible, try it and see what turns up. Theorists almost always dislike this sort of approach.
FRANCIS CRICK -
It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.

In my experience most mathematicians are intellectually lazy.
