Abstract excerpt
This paper shows that mutation frequency decline (MFD) occurs in UV-irradiated and transiently starved Escherichia coli K-12 strain AB1157. This effect involves preferential repair of pre-mutagenic lesions situated on the transcribed strand, and is mfd-, and uvrA-dependent. Mutations were tested by measuring reversion of argE3(ochre) to Arg+ and the types of reversions and the mutational specificity were defined....
