An Okazaki fragment is a relatively short fragment of DNA (with an RNA primer at the 5' terminus) created on the lagging strand during DNA replication. It was originally discovered in 1968 by Reiji Okazaki, Tsuneko Okazaki, and their colleagues while studying replication of bacteriophage DNA in Escherichia coli.
1 This type of replication is called discontinuous as the Okazaki fragments will need to be joined up later. 2  Once all of the bases are matched up (A with T, C with G), an enzyme called exonuclease strips away the primer(s). 3  The gaps where the primer(s) were are then filled by yet more complementary nucleotides.
