Chance is the only source of true novelty.
FRANCIS CRICKIf, 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.

A man who is right every time is not likely to do very much.
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 -
We have to take away from humans in the long run their reproductive autonomy as the only way to guarantee the advancement of mankind.
FRANCIS CRICK -
It is not easy to convey, unless one has experienced it, the dramatic feeling of sudden enlightenment that floods the mind when the right idea finally clinches into place.
FRANCIS CRICK -
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 -
A comparison between the triplets tentatively deduced by these methods with the changes in amino acid sequence produced by mutation shows a fair measure of agreement.
FRANCIS CRICK -
It now seems very likely that many of the 64 triplets, possibly most of them, may code one amino acid or another, and that in general several distinct triplets may code one amino acid.
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 -
How is the base sequence, divided into codons? There is nothing in the backbone of the nucleic acid, which is perfectly regular, to show us how to group the bases into codons.
FRANCIS CRICK -
Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.
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 -
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 -
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 -
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 -
Christianity may be OK between consenting adults in private but should not be taught to young children.
