Transcription-associated mutagenesis increases protein sequence diversity more effectively than does random mutagenesis in Escherichia coli.
BACKGROUND: During transcription, the nontranscribed DNA strand becomes single-stranded DNA (ssDNA), which can form secondary structures. Unpaired bases in the ssDNA are less protected from mutagens and hence experience more mutations than do paired bases. These mutations are called transcription-as...
