Answer;
They link the leading strand DNA polymerase and the lagging strand DNA polymerase together.
Explanation;
Lagging strand is one of the two strands of the DNA found at the replication fork, or junction, in the double helix, the other is the leading strand. The lagging strand requires a slight delay before undergoing replication, and must undergo replication discontinuously in small fragments. It is the work of the connector proteins to then link the lagging strand with the leading strand.
