Abstract

The neutral theory of molecular evolution predicts that the rate of evolution will be low in portions of genes and of proteins that are functionally important. This insight is the basis for bioinformatics strategies that use sequence information to make functional predictions.

Keywords:

  • amino acid sequence evolution;
  • neutral theory;
  • purifying selection;
  • protein function;
  • synonymous and nonsynonymous substitution
