Which of the following enzymes in DNA dependent RNA polymerase?

A
DNA ligase
B
Primase
C
DNA polymerase III
D
RNA transcriptase
High-Yield Explanation
DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase. Primase catalyzes the synthesis of a sho RNA (or DNA in some organisms ) segment called a primer complementary to a ssDNA template. Primase is of key impoance in DNA replication because no known replicative DNA polymerases can initiate the synthesis of a DNA strand without an initial RNA or DNA primer (for temporary DNA elongation). After this elongation, the RNA piece is removed by a 5&; to 3&; exonuclease and refilled with DNA.
