"Things are not quite what they seem always. Don't start me on class, otherwise you'll get a four-hour lecture."

"Every year, I am reminded of the kids who aren't in the freshman class and aren't graduating. I remember every single one of them. That is the worst of times for me, to see the future snuffed out."

"I honestly don't class myself as a songwriter. I've got 'musician' written on my passport. That's even funnier."

"A man who graduated high in his class at Yale Law School and made partnership in a top law firm would be celebrated. A man who invested wisely would be admired, but a woman who accomplishes this is treated with suspicion."

"To the first class belong the Gospels and Acts; to the second, the Epistles; to the third, the Revelation."

"I was just a quiet kid, really. I wasn't the class clown at all."

"The working class will not halt until socialism has been realized."

"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."

"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."

"Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid."

"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."

"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."

"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."
