[Genetic activity of aminofluorene and 2-acetylaminofluorene in strains of Saccharomycetes under conditions of in vitro metabolic activation: influence of rad 1-5 mutation].

It has been shown that the rad1-5 mutation which alters excision repair in Saccharomyces cerevisiae yeast increased reversion frequency of the ochre mutation his7-1 and the frequency of intragenic mitotic recombination in the LYS2 gene induced by 2-aminofluorene and 2-acetylaminofluorene, as compared with the wild type strains activated in vitro by 39 mix from chicken liver.
