Which is True about prokaryotic (bacterial) RNA polymerase?
A) It is used during transcription.
B) It requires a primer.
C) It has a detachable subunit, alpha factor, which recognizes the promoter.
D) It reads the template in the 5'-3' direction.
E) All of the choices are True.

Question

Quizplus · Accepted Answer

Prokaryotic RNA polymerase is used during transcription to synthesize RNA from a DNA template. It does not require a primer, has a sigma factor (not alpha) for promoter recognition, and reads the template in the 3'-5' direction while synthesizing RNA in the 5'-3' direction.
