Abstract
Size distributions of mutant clones can reveal important aspects of the mutation process. Previously published data on mutant clones induced by ethyl methanesulfonate (EMS) in bacteriophage T4 generated a distribution that was essentially flat, implying a mutagenic mechanism involving only rare mispairing by reacted bases. Here, methods for estimating the spontaneous component of such a distribution are used to generate a corrected distribution. The corrected distribution is strongly peaked, implying frequent (but not obligatory) mispairing. Frequent mispairing is in accord with current views of the fates of DNA lesions believed to mediate EMS-induced mutagenesis.
