EFFECT OF METHYLENE BLUE ON THE ACTION OF 4-NITROQUINOLINE N-OXIDE AND ACRIFLAVINE IN INDUCING RESPIRATION-DEFICIENT MUTANTS OF SACCHAROMYCES CEREVISIAE

Abstract

Methylene blue which was almost ineffective in the production of respirationdeficient mutants of Saccharomyces cerevisiae suppressed the induction of the same mutants by acriflavine but did not show any effect on the mutation induced by 4-nitroquinoline N-oxide.
