Summary
We have isolated a number of heat sensitive mutants of the yeast, Saccharomyces cervisiae. These mutants are sensitive to heat inactivation at 52°C and 37°C. They are also sensitive to the monofunctional alkylating agent EMS and are sensitive to gamma rays at low doses. The results suggest a common step in the repair of some of the damage induced by heat, alkylating agents and ionizing radiation.
