NEET Biology question

In prokaryotes, the process of replication is catalysed by the following enzymes. Identify which of the enzymes is best coordinate with role.

(A)Helicase – Joins the ends of DNA segments
(B)DNA polymerase-I – Synthesises DNA
(C)DNA polymerase-II – Erases primer and fills gaps
(D)Primase – Synthesises RNA primersCorrect

Answer: (D)

Solution

Primase synthesises the short RNA primers needed to initiate DNA synthesis. Helicase unwinds the double helix (not joins segments — that is ligase's role), DNA polymerase I removes RNA primers and fills the resulting
