Vedclass · Answer

(B) In prokaryotes,the $RNA$ polymerase enzyme consists of a core enzyme and a sigma factor $(\sigma)$.The core enzyme is responsible for the polymerization of ribonucleotides.The sigma factor $(\sigma)$ specifically recognizes the promoter site on the $DNA$ template.When the sigma factor binds to the $RNA$ polymerase,it facilitates the binding of the enzyme to the promoter region,thereby initiating the process of transcription.Therefore,the sigma factor is essential for the initiation of transcription.

What happens when the sigma factor $(\sigma)$ binds to the $RNA$ polymerase?
