Deskripsi

Transcription elongation by RNA polymerase (RNAP) is interspersed with sequence-dependent pausing which is difficult to study due to spatiotemporal limitations of available methods. Here authors use a high-resolution optical tweezers assay and find that pause sites modify the dynamics of nearly all RNAP molecules.
