Francis Crick
"For 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."
Quote_1.png
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."
Quote_1.png
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."
Quote_1.png
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."
Quote_1.png
Francis Crick
"The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority."
Quote_1.png
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."
Quote_1.png
Francis Crick
"Attempts have been made from a study of the changes produced by mutation to obtain the relative order of the bases within various triplets, but my own view is that these are premature until there is more extensive and more reliable data on the composition of the triplets."
Quote_1.png
Francis Crick
"It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule."

"We've discovered the secret of life."
Quote_1.png
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."
