During DNA replication, Okazaki fragments are used to elongate:
Correct answer: C. The lagging strand away from the replication fork
- A. The lagging strand towards the replication fork
- B. The leading strand away from replication fork
- C. The lagging strand away from the replication fork
- D. The leading strand towards the replication fork
Explanation
A lagging strand is a replicated strand of DNA that is formed in short segments called Okazaki fragments. Its growth is discontinuous. The direction of growth of the lagging strand is 3' ➡ 5' though in each Okazaki fragment, it is 5' ➡ 3'.

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.
