Ethidium bromide (EB) and ultraviolet light (UV) in combination are known to produce a synergistic induction of "petite" mutants in yeast. Two other agents were combined with EB, 3-Carbethoxypsoralene (3 CPs) activated by 365 nm light or gamma rays. EB in combination with 3 CPs also resulted in an e
Sequence changes in mutations induced by ultraviolet light are reported for the chromosomal Escherichia coli gpt gene in almost isogenic E. coli uvr+ and excision-deficient uvrA cells. Differences between the mutagenic spectra are ascribed to preferential removal of photoproducts in the transcribed
