This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
During replication of DNA, which one of the following  enzymes polymerizes the Okazaki fragments? 
Select and explain. 
A. DNA Polymerase I, B. DNA Polymerase II, C. DNA Polymerase III, D. RNA Polymerase
C: DNA Polymerase III
Answer: C: DNA Polymerase III 
Explanation: 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.
