WebOkazaki fragment maturation. During Okazaki fragment maturation, (i) Pol δ displaces a short segment of the initiator primer into a 5′ flap; (ii) FEN1 recognizes the displaced flap, binds to the base of the flap and cleaves the flap; (iii) DNA ligase seals the nick; (iv) certain flaps are elongated by the action of the 5′–3′ helicase ... WebOkazaki fragments are the part of lagging strands. They are short, newly synthesized DNA fragments formed on the lagging template strand during DNA replication. They are complementary to the lagging template strand, together forming short, double-stranded DNA sections. DNA is synthesized from 5' to 3' direction.

These are synthesized by DNA polymerase … Okazaki fragments are present in both prokaryotes and eukaryotes. DNA molecules in eukaryotes differ from the circular molecules of prokaryotes in that they are larger and usually have multiple origins of replication. This means that each eukaryotic chromosome is composed of many replicating units of DNA with multiple origins of replication. In comparison, prokaryotic DNA has only a single origin of replication. In eukaryotes, these replicating forks, which are numerous all …
