Backtracking by single RNA polymerase molecules observed at near-base-pair resolution

Escherichia coli RNA polymerase (RNAP) synthesizes RNA with remarkable fidelity in vivo1. Its low error rate may be achieved by means of a ‘proofreading’ mechanism comprised of two sequential events. The first event (backtracking) involves a transcriptionally upstream motion of RNAP through several...
