Q150 / 200 · NEET 2024 (Re-NEET) · Zoology
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 :
- Correct answerAStatement I is true but Statement II is false
- BStatement I is false but Statement II is true
- CBoth Statement I and Statement II are true
- DBoth Statement I and Statement II are false
Solution
The RNA polymerase is only capable of catalysing the process of elongation, thus, statement I is correct.
RNA polymerase associates transiently with initiation-factor $(\sigma)$ and termination-factor $(\rho)$ to initiate and terminate the transcription. Thus, statement II is incorrect.
Hence, the correct answer is option: 'A'.
