The sliding clamp complex encircles the DNA template and binds to DNA polymerase. This helps the polymerase synthesize much longer stretches of DNA without dissociating
While the loading of the clamp only occurs once on the leading strand, it must happen each time a new Okazaki fragment is made on the lagging strand. How does the cell expedite this process?
The cell employs an additional protein in order to make the constant reloading of the sliding clamp on the lagging strand much more efficient. The protein, called the clamp loader, harnesses energy from ATP hydrolysis to lock a sliding clamp complex around the DNA for every successive round of DNA synthesis.
