The Genetic Basis of Mutation Rate Variation in Yeast. [PDF]
, 2018 Mutations are the root source of genetic variation and underlie the process of evolution. Although the rates at which mutations occur vary considerably between species, little is known about differences within species, or the genetic and molecular basis ...
