diploid cells of the wild-type yeast saccharomyces cerevisiae , mutants homozygous with respect to rad2 and rad54 loci as well as a double mutant with both these loci in homozygous state were used to demonstrate the previously observed ( in other yeast strains ) genetic determination of radiosensitivity modification of hypoxic cells by oxygen and electron-affinic compounds .
