Okazaki fragments

Okazaki fragments
the short fragments of DNA, each consisting of an RNA primer and a short DNA chain and ranging in length from 100–200 nucleotides in eukaryotes to 1000–2000 nucleotides in prokaryotes, formed in synthesis of the lagging strand during DNA replication; later the primers are replaced by DNA and the fragments are joined by DNA ligase to form a continuous strand. See illustration at replication fork, under fork.
