Transcriptional bypass of bulky DNA lesions causes new mutant RNA transcripts in human cells.

Abstract excerpt

Here, we characterize the mutant transcripts resulting from bypass of an 8,5'-cyclo-2'-deoxyadenosine (cyclo-dA) or cyclobutane pyrimidine dimer (CPD) by human RNA polymerase II (Pol II) in vivo. With the cyclo-dA lesion, we observed two new types of mutant transcripts. In the first type, the polymerase inserted uridine opposite the lesion and then misincorporated adenosine opposite the template deoxyadenosine...
