Comparison of the effects of ultraviolet light and ethylmethanesulphonate upon the frequency of mitotic recombination in yeast

Molecular and General Genetics MGG Aims and scope Submit manuscript

Summary

Diploid cultures of the yeast Saccharomyces cerevisiae were treated with UV light and ethylmethanesulphonate and scored for mitotic recombination and cell survival. Intergenic recombination was induced to the same frequency by both treatments at the same survival level whereas EMS induced more intragenic recombinants than UV treatment at the same survival.

The mechanisms of induction of both recombinational events are discussed.
