Explanation:
Detailed explanation-1: -Each section begins with an RNA primer. This discontinuous synthesis results in the generation of fragments on the lagging strand called Okazaki fragments. DNA polymerase I recognizes a “nick” or break in the phosphate backbone, and then removes each RNA primer and fills the gaps with DNA.
Detailed explanation-2: -On the lagging strand, DNA synthesis restarts many times as the helix unwinds, resulting in many short fragments called “Okazaki fragments.” DNA ligase joins the Okazaki fragments together into a single DNA molecule.
