Abstract excerpt
During transcription, prokaryotic and eukaryotic RNA polymerases bypass and misread (transcriptional mutagenesis) several classes of DNA lesions. For example, misreading of 8-OH-dG generates mRNAs containing G to T transversions. After translation, if the mutant protein briefly allowed the cell a growth-DNA replication advantage, then precocious DNA replication would bypass that unrepaired 8-OH-dG and misinsert...
