The distribution of spontaneous erythromycin-resistant mutants as a function of cell-cycle stage was examined in Saccharomyces cerevisiae. The overall frequency of erythromycin-resistant mutants was much lower than NG (nitrosoguanidine)-induced mutagenesis. The level of mutagenesis was the same at all stages of the cell cycle. NG results in enhanced mutation during periods of active DNA synthesis.
