Answer:
The answer is: DNA polymerase on the leading strand is "stuck" to the DNA polymerase on the lagging strand.
Explanation:
The DNA polymerase on the leading strand is "stuck" to the DNA polymerase on the lagging strand so that both strands can be synthesized in the same direction for coordination to be fulfilled such as: a replication loop is formed, leading and lagging strand synthesis are coupled, and the lagging strand polymerase recycles from one fragment to another single-stranded DNA-binding protein.
