Detailed explanation-1: -What are Okazaki Fragments For? Okazaki fragments are short sections of DNA formed at the time of discontinuous synthesis of the lagging strand during replication of DNA. It is essential as it allows for the synthesis of both the daughter strands required for cell division.

Detailed explanation-2: -Okazaki fragments are small sections of DNA that are formed during discontinuous synthesis of the lagging strand during DNA replication. They are important because they allow for both daughter strands to be synthesized, which are necessary for cell division.

Detailed explanation-3: -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-4: -Lagging-strand replication is discontinuous, with short Okazaki fragments being formed and later linked together.

Detailed explanation-5: -Discontinuous DNA synthesis occurs from the 5’ end to the 3’ end of the parent strand. This strand is often referred to as the lagging strand. It is completed in short sequences of nucleotides called Okazaki fragments. Replication on the lagging strand begins with the addition of an RNA primer by the enzyme primase.
