Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.

Anybody who believes that the earth is less than 10,000 years old needs psychiatric help.

If the code does indeed have some logical foundation then it is legitimate to consider all the evidence, both good and bad, in any attempt to deduce it.
FRANCIS CRICK

Bad Evidence Foundation Goodness Legal Logic
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.

If revealed religions have revealed anything it is that they are usually wrong.

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

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.

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.

A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.
FRANCIS CRICK

Detail Evidence Ideas Ourselves Science Type
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.

Avoid the temptation to work so hard that there is no time left for serious thinking.

Avoid Serious Temptation Thinking Time
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.

Since I essentially knew nothing, I had an almost completely free choice.

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.
