Abstract

SUMMARY: The formation of single-stranded breaks in DNA following UV irradiation is assessed in 34 mutants. By altering the SOS DNA-repair system, either by additional mutations or by using drugs affecting transcription or translation, it is shown that such single-stranded breaks require one or more DNA-damage-inducible functions. A UV-sensitive strain is characterized as carrying a Tn insertion into the gene. The absence of post-irradiation incision in this strain demonstrates that function is absolutely required for the incision stage of excision repair, and suggests that other mutants are ‘leaky’.
