What happens during lagging strand synthesis?

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. ... RNA primers are removed and replaced with DNA by DNA polymerase I.

Is the lagging strand synthesized?

The leading strand is synthesized in a continuous manner, whereas synthesis of the lagging strand requires a primase that makes RNA primers that are extended by the DNA polymerase to form Okazaki fragments — short DNA fragments that are processed to produce a continuous DNA strand.
