Question

Which of the following is a correct comparison between RNA polymerase holoenzyme that functions in transcription and the primase enzyme that functions in DNA replication?

A) Both enzymes synthesize RNA
B) Both enzymes are bound by sigma factor
C) Both enzymes shnthesize DNA
D) Both enzymes are composed of RNA

Answer 1

Option A

Step-by-step explanation:

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it.

And since primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
