Abstract excerpt
LacI- mutants obtained following 2 and 6 h of thymine deprivation were cloned and sequenced. The mutational spectra recovered were dissimilar. After 2 h of starvation the majority of mutations were base substitutions, largely G:C----C:G transversions. Frameshift mutations but not deletions were observed. In contrast, following 6 h of starvation, with the exception of the G:C----C:G transversion, all possible base...
