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.

There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.

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.

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.

It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.

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.

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.

You can do reverse engineering, but you can’t do reverse hacking.

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.

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

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.

Population when unchecked increases in a geometrical ratio. Subsistence only increases in an arithmetical ratio.

Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes... can no longer be of concern to great powers alone.

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

I don't like the country. The crickets make me nervous.

So down thy hill, romantic Ashbourn, glides The Derby dilly, carrying three INSIDES.

Ah! soul of mine! Ah! soul of mine! Thy sluggish senses are but bars That stand between thee and the stars, And shut thee from the world divine.

It's impossible to be content all the time - you have to learn to be content in places where you're unhappy and owning your emotions, whatever they are.

... the fouling of the nest which has been typical of man's activity in the past on a local scale now seems to be extending to the whole world society.

Seeing is in itself a movement.

The same contingencies of time and space that force a statesman or soldier to make decisions, impel the historian, though with less urgency, to make up his mind.
