Question

This enzyme is a multi-protein complex that performs most DNA replication and has both 5' -> 3' polymerase activity and 3'-> 5' exocunlease activity?

Answer 1

DNA polymerase III is a multi-protein complex that performs most DNA replication and has both 5'->3' polymerase activity and 3'->5' exonuclease activity. It adds nucleotides to the growing DNA chain, removes RNA primer, and seals gaps on the lagging strand.

Step-by-step explanation:

The enzyme that performs most DNA replication and has both 5'->3' polymerase activity and 3'->5' exonuclease activity is DNA polymerase III.

DNA polymerase III is a multi-protein complex that adds nucleotides to the growing DNA chain in the 5'->3' direction and is involved in proofreading and repair.

The enzyme removes RNA primer and replaces it with newly synthesized DNA. Additionally, DNA polymerase III seals the gaps between the Okazaki fragments on the lagging strand to create one continuous DNA strand.
