Question

The RNA polymerase holoenzyme transcribes the promoter, structural gene, and terminator. Justify this statement.

Answer 1

Transcription:

1. The process of copying a segment of DNA into RNA is called transcription.
2. It is a three-step process.
3. The first step is initiation, followed by elongation, and termination.
4. Firstly, the initiation factor recognizes the start signal.
5. Then, it promotes a region in the DNA.
6. Then the DNA region along with RNA polymerase binds to the promoter and initiates the transcription.
7. The RNA polymerase is separated from the DNA-RNA hybrid.
8. As a result of this separation, the nascent RNA separates.
9. This process is called termination.
10. Termination is facilitated by a termination factor.
11. Thus, RNA polymerase holoenzyme transcribes the promoter, structural gene and terminator.
