Which of the following if TRUE regarding prokaryotic DNA polymerase?
(I) Abortive initiation is common.
(II) RNA polymerase processivity increases with the β clamp.
(III) The error rate is 1 in 10⁶.
(IV) Initiation of transcription begins at the −10 position.

Question

Quizplus · Accepted Answer

(I) is true for prokaryotic RNA polymerase, not DNA polymerase. 
(II) is also true for RNA polymerase and not DNA polymerase. 
(III) is not a valid statement as it does not provide any meaningful information. 
(IV) is true for prokaryotic DNA polymerase, but it is not included in the correct answer, as it is not the only true statement. 
Therefore, the only true statement about prokaryotic DNA polymerase is (I), which states that 'Abortive initiation is common.'
