Detailed explanation-1: -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 formed on the lagging strand away from the replication fork and later joined by the enzyme DNA ligase.
Detailed explanation-3: -Okazaki fragments are then synthesized via extension of these RNA primers by DNA polymerase. An important consequence of such RNA priming is that newly synthesized Okazaki fragments contain an RNA-DNA joint, the discovery of which provided critical evidence for the role of RNA primers in DNA replication.
