Detailed explanation-1: -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.
Detailed explanation-2: -Which of the following statements best describes Okazaki fragments? They are formed in the lagging strand. Okazaki fragments are short sequences synthesized in the lagging strand because DNA polymerase can synthesize only from 5′ to 3′, and the DNA strands are antiparallel.
Detailed explanation-3: -The second strand or the lagging strand is synthesized discontinuously in the 5′ to 3′ direction in the small fragments. These are called Okazaki fragments.
Detailed explanation-4: -Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.
