Caption: A new model of DNA repair is revealed in a new study. In this model, RNA polymerase patrols tracks of double-stranded DNA and stalls over damaged areas. An enzyme called UvrD helicase pulls the blocked RNA polymerase off the tracks, exposing broken DNA to repair. After the repair, the polymerase continues along the tracks.
