WebMar 1, 2024 · The next step of transcription is called promoter clearance or promoter escape. RNA polymerase must clear the promoter once the first bond has been synthesized. The promoter is a DNA sequence that signals which DNA strand is transcribed and the direction transcription proceeds. WebIt occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready …
