title: The probability with which EMS-initiated mutagenic lesions generate mutations in CHO cells.
abstract: In this note we distinguish between multiple mutations affecting a given locus which are generated at separate error-prone lesions and multiple independent mutations generated at a single error-prone lesion. We describe a basis for determining the probability with which the latter class of mutations occurs based on the mutant fraction in the progeny and determine an average probability of 0.6 mutations/replication/mutagenic site for those EMS-modified sites which are mutagenic for G6PDH activity in CHO cells.
