Vedclass · Answer

(A) In prokaryotic transcription, the $RNA$ polymerase enzyme consists of a core enzyme and a sigma factor $(\sigma)$.The core enzyme is responsible for the elongation of the $RNA$ chain.The sigma factor $(\sigma)$ specifically recognizes the promoter region on the $DNA$ template.By binding to the promoter, the sigma factor facilitates the initiation of transcription.Once initiation is complete, the sigma factor dissociates from the core enzyme, allowing elongation to proceed.

In the process of transcription, the sigma factor is important for:
