Reiterative Transcription

Reiterative Transcription

alternative pathways for transcription

Schematic of alternative pathways for transcription elongation complex formation. During canonical transcription (left) the growing strand of RNA extends toward the RNA exit channel of RNA polymerase. New, high-resolution crystal structure determined in this study shows that during reiterative transcription (right) the RNA extends toward the main channel of RNA polymerase.
