MHT CET Biology question

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

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

Answer: (D)

Solution

Helicase unwinds DNA (ligase joins ends), so (a) is wrong; the main synthesis of DNA segments is by DNA polymerase-III and DNA polymerase-I is the one that
