Question

What enzyme is responsible for adding RNA primers?

(a) DNA Primase
(b) RNA Polymerase
(c) RNA Ligase
(d) DNA Helicase

Answer 1

The enzyme responsible for adding RNA primers is DNA Primase, which creates short RNA segments to initiate DNA synthesis.

Step-by-step explanation:

The enzyme responsible for adding RNA primers during DNA replication is DNA Primase. It synthesizes a short RNA segment, typically about five to ten nucleotides long, which is complementary to the template DNA strand. This RNA segment is essential because DNA polymerases require a primer from which to begin DNA synthesis since they can only add nucleotides to an existing strand. The correct answer to the question is therefore (a) DNA Primase.
