NEET Botany Transcription MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about RNA polymerase and transcription is correct?
A
RNA polymerase catalyzes initiation, elongation, and termination independently.
B
RNA polymerase requires initiation and termination factors for transcription.
C
Only elongation is catalyzed by RNA polymerase without any factors.
D
The nascent RNA remains bound to RNA polymerase throughout transcription.
Correct Answer
Option B
Detailed Explanation
RNA polymerase is capable of catalyzing elongation, but it associates with initiation-factor (σ) and termination-factor (ρ) for initiation and termination, respectively. This indicates that RNA polymerase relies on these factors to complete the transcription process.
