During abortive Transcription, RNA Polymerase Remains Stationary and Pulls Downstream DNA into Itself

RNA polymerase produces and releases short RNA transcripts of 10 nucleotides (abortive synthesis) before escaping the promoter, entering the elongation phase, and synthesizing the proper transcript. It has long been unclear how the enzyme’s active site translocates along the DNA template during initial abortive cycles of transcription. Three general models were proposed:- “transient excursion”, “Inchworming”, “Scrunching”
