Question

Strand initiation during replication is carried out by an enzyme that makes a short RNA molecule that is used as a primer; the enzyme is a distinct type of RNA polymerase, called _______.

a. RNA gyrase
b. RNA ligase
c. ribonuclease
d. primase
e. deoxyribonuclease

Answer 1

The enzyme that makes a short RNA molecule used as a primer during strand initiation of replication is called primase.

Step-by-step explanation:

Strand initiation during replication is carried out by an enzyme that makes a short RNA molecule used as a primer. The enzyme responsible for strand initiation during replication by making a short RNA molecule that acts as a primer is called primase. This enzyme is a distinct type of RNA polymerase, called primase. Primase is involved in the creation of an RNA primer, which is a short complementary sequence of RNA nucleotides synthesized on the template strand, allowing DNA polymerase to begin the synthesis of the new DNA strand. During replication, the enzyme DNA polymerase III then utilizes this primer to synthesize the daughter DNA strand.
