Their books are also different. Works of fiction contain a single plot, with all its imaginable permutations. Those of a philosophical nature invariably include both the thesis and the antithesis, the rigorous pro and con of a doctrine. A book which does not contain its counterbook is considered incomplete. ↗

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. ↗

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. ↗

The function of literature, through all its mutations, has been to make us aware of the particularity of selves, and the high authority of the self in its quarrel with its society and its culture. Literature is in that sense subversive. ↗

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 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. ↗

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway. ↗

First of all, many human diseases are influenced by, if not caused by mutations in genes. ↗

Although I insist that God has always had the power to intervene directly in nature to create new forms, I am willing to be per-suaded that He chose not to do so and instead employed secondary natural causes like random mutation and natural selection. ↗

In microbiology the roles of mutation and selection in evolution are coming to be better understood through the use of bacterial cultures of mutant strains. ↗
