"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."

"It was inevitable that in doing this I should arrive at new results, and it is perhaps understandable that in the end I have felt impelled to present these results not only in the dry form of a catalogue, but also in a more connected and personal one."
"What most experimenters take for granted before they begin their experiments is infinitely more interesting than any results to which their experiments lead."
"I became a better listener than I ever had been as a result of playing Jean Luc Picard because it was one of the things that he does terrifically well."
"In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a spectral line appeared to me to be the result of the coherence and co-operation of several electric quanta."
"I want to be as honest as I can about the things I've been through - the sorrows and joys, victories and defeats - and to use those experiences as a well to draw from. Hopefully, the songs that result from that kind of writing will be songs that mean something to others."

"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."
"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."
"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."
"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."
"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."
"It 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."
"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."
"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."
"Do codons overlap? In other words, as we read along the genetic message do we find a base which is a member of two or more codons? It now seems fairly certain that codons do not overlap."
