Summary Introduction
To review:
The mechanism that releases positive supercoils in the DNA (Deoxyribonucleic acid) which help DNA polymerase to move along the DNA template during the transcription process.
Introduction:
Transcription is the process in which the DNA sequences of a gene are copied to produce RNA (Ribonucleic acid). RNA polymerase acts as the main transcription enzyme. The process of transcription proceeds in three stages: initiation, elongation, and termination. Initiation is the beginning of transcription, elongation is the
