Vedclass · Answer

(A) The sigma factor $\sigma$ is a subunit of the $RNA$ polymerase holoenzyme. Its primary role is to recognize the promoter site on the $DNA$ template to initiate transcription. Once the transcription process moves from the initiation phase to the elongation phase, the sigma factor dissociates from the $RNA$ polymerase core enzyme. Therefore, during the elongation of the polypeptide chain, the sigma factor is functionless in the context of the elongation complex.

During elongation of the polypeptide chain, the sigma factor is
