Better late than never for repair of miscoding lesions within a transcribed template.
Transcription does not always stall at base damage in DNA and can create mutated transcripts from miscoding lesions. In this issue of Molecular Cell, present genetic analysis of E. coli to indicate that the highly mutagenic purine modification, 8-oxoguanine, is subject to transcription-coupled repair despite transcriptional bypass and generation of mutant transcripts.
