An Okazaki fragment is a short length of DNA used to form a growing lagging strand in replicating DNA. Okazaki fragments allow the lagging strand to be synthesized in the 5' to 3' direction while the strand actually grows in the direction of the replication fork (3' to 5').n Okazaki fragment is a short length of DNA used to form a growing lagging strand in replicating DNA.
