Which of the following enzymes in DNA dependent RNA polymerase?
DNA ligase
Primase
DNA polymerase III
RNA transcriptase
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.
