DNA leading strand is constructed through DNA polymerase III whereas Okazaki fragments are constructed through:
Correct answer: B. DNA polymerase III
- A. DNA polymerase I
- B. DNA polymerase III
- C. DNA polymerase II
- D. DNA Ligase
Explanation
DNA polymerase III is the main replicating enzyme. It has two subunits. Both leading and lagging strands are constructed by DNA polymerase III. Each Okazaki fragment is synthesised by DNA polymerase III in a 5' → 3' direction.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
