Question

Given below are two statements regarding RNA polymerase in prokaryotes.

Statement I : In prokaryotes, RNA polymerase is capable of catalysing the process of elongation during transcription.

Statement II : RNA polymerase associate transiently with ‘Rho’ factor to initiate transcription.

In the light of the above statements, choose the correct answer from the options given below :

(1) Statement I is true but Statement II is false

(2) Statement I is false but Statement II is true

(3) Both Statement I and Statement II are true

(4) Both Statement I and Statement II are false

Answer 1

Correct option is (1) Statement I is true but Statement II is false

The RNA polymerase is only capable of catalysing the process of elongation, thus, statement I is correct.

RNA polymerase associates transiently with initiation-factor (\(\sigma\)) and termination-factor (\(\rho\)) to initiate and terminate the transcription. Thus, statement II is incorrect.
