I. Determination of the quantum yield of thymidine dinucleoside irradiated by ultra-violet light. II. Studies on the inactivation by ultra-violet light of T_4D bacteriophage containing 5-bromodesoxyuridine substituted DNA
It has been found that when frozen thymine solutions are irradiated by ultra-violet light a photoreversible steady state is formed between thymine and a thymine diner. The suggestion has been made that such photoreversible chemical reactions might be involved in the photoreactivable mutations that o...
