Question

DNA polymerase is processive, which means that it remains tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter strand. Which piece of the DNA replication machinery accounts for this characteristic?

Answer 1

Answer: DNA sliding clamp

Explanation:

The procesivity ability of DNA polymerase is attributed to a protein DNA sliding clamp, a component of DNA polymerase III holoenzyme.

A DNA clamp keeps DNA polymerase processive, during replication. The sliding clamp keeps DNA polymerase tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter strand.
