Free will is located in or near the anterior cingulate sulcus.
FRANCIS CRICKFree will is located in or near the anterior cingulate sulcus.
FRANCIS CRICKThe 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 CRICKThe ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.
FRANCIS CRICKFor simplicity one can think of the + class as having one extra base at some point or other in the genetic message and the – class as having one too few.
FRANCIS CRICKThe dangerous man is the one who has only one idea, because then he’ll fight and die for it.
FRANCIS CRICKA good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
FRANCIS CRICKIt 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 CRICKIn my experience most mathematicians are intellectually lazy.
FRANCIS CRICKThere is no form of prose more difficult to understand and more tedious to read than the average scientific paper.
FRANCIS CRICKIt 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 CRICKI 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 CRICKIt is notoriously difficult to define the word living.
FRANCIS CRICKHow 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 CRICKIt 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 CRICKProtein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.
FRANCIS CRICKIt 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.
