Question

Which factor is important for termination of transcription?

• A. $\sigma$ (sigma)
• B. $\rho$ (rho)
• C. $\gamma$ (gamma)
• D. $\alpha$ (alpha)

Hint:

Rho ($\rho$) = Termination. \quad Sigma ($\sigma$) = Initiation.

Answer 1

The Correct Option is B

The rho ($\rho$) factor is a protein involved in the termination of transcription in prokaryotes. It binds to specific sequences in the newly synthesized RNA and acts as a helicase to unwind the DNA-RNA hybrid, leading to the release of the RNA polymerase and termination of transcription. Sigma factor is involved in initiation, not termination.
