Detailed explanation-1: -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-2: -In DNA replication, Okazaki fragments are formed as double-stranded intermediates during synthesis of the lagging strand. They are composed of the growing DNA strand primed by RNA and the template strand.
Detailed explanation-3: -The discontinuous short sequences of DNA nucleotides are known as Okazaki fragments. The formation of Okazaki fragments occurs during the process of DNA replication to synthesize the lagging strand of DNA.
Detailed explanation-4: -Complete Answer: Okazaki fragments are discontinuous short sequences of DNA nucleotides and are formed during the DNA replication process to synthesize the lagging strand of DNA. After being discontinuously synthesized, these fragments are joined together by enzyme DNA ligase.
Detailed explanation-5: -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. Helicase opens up the DNA at the replication fork.
