Detailed explanation-1: -On the leading strand, DNA synthesis occurs continuously. 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.

Detailed explanation-2: -The lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are ultimately stitched together. The leading strand is synthesized at twice the rate of the lagging strand.

Detailed explanation-3: -This is known as leading strand synthesis, and it take places in a continuous manner. DNA copied from the other template strand, on the other hand, is discontinuous.

Detailed explanation-4: -This enzyme can work only in the 5’ to 3’ direction, so it replicates the leading strand continuously. Lagging-strand replication is discontinuous, with short Okazaki fragments being formed and later linked together.
