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.

If poly A is added to poly U, to form a double or triple helix, the combination is inactive.

A man who is right every time is not likely to do very much.

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

A busy life is a wasted life.

One immediately sees how many previously puzzling facts are neatly explained by the new hypothesis. One could kick oneself for not having the idea earlier, it now seems so obvious. Yet before, everything was in a fog.

This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.
