Question

Regarding prokaryotes, the sigma factor, once it brings the RNA polymerase to the correct promoter sequence, is ejected.

A. True
B. False

Answer 1

The sigma factor in prokaryotes helps RNA polymerase recognize and bind to the promoter sequence before being ejected.

Step-by-step explanation:

In prokaryotes, the sigma factor plays a crucial role in transcription initiation. It binds to the RNA polymerase and helps it recognize and bind to the promoter sequence of a gene. Once the RNA polymerase is properly aligned with the promoter, the sigma factor is ejected and the transcription process begins. Therefore, the statement is True.
