title: Terminal strand-switching of E. coli RNA polymerase transcribing a truncated DNA fragment.
abstract: When transcribing a restriction fragment containing the promoters and the first part of the rrnE operon of Escherichia coli, RNA polymerase holoenzyme starts exclusively on the promoters. Besides run-off transcripts, molecules longer than template-size are formed by terminal strand switch.
