Answer» Correct choice is (a) it is assumed that each amino acid position is equally mutable

Explanation: In this process, first, it is assumed that each amino acid position is equally mutable, whereas, in fact, sites vary considerably in their degree of mutability. Mutagenesis hot spots are well known in molecular genetics, and variations in mutability of different amino acid sites in proteins are well known.
