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.
