Question

Given below are two statements regarding RNA polymerase in prokaryotes.
Statement I : In prokaryotes, RNA polymerase is capable of catalysing the process of elongation during transcription.
Statement II : RNA polymerase associate transiently with ‘Rho’ factor to initiate transcription.
In the light of the above statements, choose the correct answer from the options given below :

• A. Statement I is true but Statement II is false
• B. Statement I is false but Statement II is true
• C. Both Statement I and Statement II are true
• D. Both Statement I and Statement II are false

Answer 1

The Correct Option is A

Statement I: Prokaryotic RNA polymerase is responsible for the elongation phase of transcription. Correct

Statement II: The Rho factor is involved in termination, not initiation of transcription. RNA polymerase interacts with sigma factor (σ) for initiation and with Rho factor (ρ) for termination. Incorrect
