Question

Which factor is required for the initiation of transcription in Prokaryotes?

RankGuru · Accepted Answer

1. **Enzyme**: Prokaryotic RNA polymerase (holoenzyme) is responsible for transcription.
2. **Initiation**: To specifically recognize and bind to the promoter region, the core enzyme must associate with the **sigma ($σ$) factor**.
3. **Elongation**: After initiation, the sigma factor dissociates and the core enzyme continues elongation.
4. **Termination**: The **rho ($ho$) factor** is required for termination.
5. **Conclusion**: Sigma factor is required for initiation.
