| Research Abstract |
Mitochondrial RNA polymerase (mtRNAP) catalyzes the synthesis of essential transcripts in mitochondria where reactive oxidative (ROS) species are generated as byproducts. The occurrence of RNA synthesis by mtRNAP at oxidative DNA lesions remains unknown. Purified mtRNAP and a complex of RNA primer/DNA template containing a single DNA lesion were used for in vitro RNA synthesis assays. We show that mtRNAP bypassed the oxidative DNA lesion.
