[Characteristics of the range of mutations in nystatin resistance induced in yeasts by 6-N-hydroxylaminopurine].

: A simple procedure for induction of nistatin-resistant mutants in yeasts under the action of 6-N-hydroxylaminopurine (HAP) is proposed. Some differences between the spectra of mutations induced by HAP and UV-light are observed: HAP induces dominant and double recessive mutants more frequently.
