The enzyme that attaches the Okazaki fragments in the lagging strand is called:
Correct answer: D. DNA Ligase
- A. Restriction endonuclease
- B. Primase
- C. DNA helicase
- D. DNA Ligase
Explanation
The enzyme that attaches the Okazaki fragments in the lagging strand during DNA replication is called DNA ligase. DNA ligase is responsible for sealing the nicks or gaps between the Okazaki fragments by catalysing the formation of phosphodiester bonds between adjacent nucleotides. This process results in a continuous and complete lagging strand.

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.
