| Abstract: | Summary A procedure for the determination of the frequency of mating type switching in heterothallic strains of Saccharomyces cerevisiae was worked out. In cell populations irradiated with X-rays the frequencies of switching were enhanced in a dose-dependent manner. The possible implication of this finding for understanding the mechanism of carcinogenesis is discussed. |
