Question

This protein is present at every replication fork and prevents dna polymerase from dissociating, but does not impede the rapid movement of the enzyme.

Answer 1

The DNA clamp/sliding clamp is the protein that is present at every replication fork and prevents DNA polymerase from dissociating but does not impede the rapid movement of the enzyme. It is a protein fold that serves as a processivity promoting factor in DNA replication.
