The Transition from Transcriptional Initiation to Elongation Involves

Question

The transition from transcriptional initiation to elongation involves
A)binding of sigma factor.
B)release of sigma factor.
C)release of RNA polymerase from DNA.
D)binding of RNA polymerase to DNA.
E)binding of rho factor.

Accepted Answer

The transition from transcriptional initiation to elongation in bacteria involves the release of sigma factor from the RNA polymerase complex. Sigma factor is crucial for initiation because it helps the RNA polymerase to recognize and bind to specific promoter regions on the DNA. Once transcription is initiated, the sigma factor is released, allowing RNA polymerase to proceed with elongation of the nascent RNA transcript.
