During replication of DNA, which one of the following  enzymes polymerizes the Okazaki fragments?: (A) DNA Polymerase I, (B) DNA Polymerase II, (C) DNA Polymerase III, (D) RNA Polymerase
Answer is C. On 5’----> 3’ Strand (Lagging Strand/Discontinuous Strand/Retrograde Strand).
Synthesized in discontinuous manner.
Small fragments of DNA are in short spurts of 100–250 nucleotide (1000–2000 bp in prokaryotes) called Okazaki fragment synthesized in 5’ --- 3’ direction.

By  DNA Polymerase III in prokaryotes.
By DNA Polymerase δ  in eukaryotes.
