ABSTRACT

Phenotypic repair by streptomycin has been studied in amber mutants of phage T4 on su- strains, as has the interference of SmR mutations with amber suppressors. The repair seems not to be specific; however a temporal specificity of streptomycin action has been demonstrated by means of pulse experiments. The dependence of the efficiency of suppression upon experimental condition is also reported.
