Lack of dependance of transcription-induced cytosine deaminations on protein synthesis.

Transcription-induced mutations (TIM) is a phenomenon in Escherichia coli in which transcription promotes C to T and other mutations in a strand-specific manner. Because the processes of transcription and translation are coupled in prokaryotes and some models regarding creating a hypermutagenic state in E. coli require new protein synthesis, we tested the possibility that TIM was dependent on efficient synthesis of proteins.
