The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.

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.

Free will is located in or near the anterior cingulate sulcus.

Again the message to experimentalists is: Be sensible but don’t be impressed too much by negative arguments. If at all possible, try it and see what turns up. Theorists almost always dislike this sort of approach.

There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.

The dangerous man is the one who has only one idea, because then he’ll fight and die for it.

Dangerous Death Fight Himself Ideas Thinking
When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There’s something that might be called the ‘graduate student syndrome’; graduate students hardly believe they can make a discovery.

A knowledge of the true age of the Earth and of the fossil record makes it impossible for any balanced intellect to believe in the literal truth of every part of the Bible in the way that fundamentalists do.

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.

Exploratory research is really like working in a fog. You don’t know where you’re going. You’re just groping. Then people learn about it afterwards and think how straightforward it was.

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

Agreement Comparison Measurement Production
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.

Trying to determine the structure of a protein by UV spectroscopy was like trying to determine the structure of a piano by listening to the sound it made while being dropped down a flight of stairs.
