The formation of a new strand of DNA from a template strand is the function of:
Correct answer: A. DNA polymerase
- A. DNA polymerase
- B. RNA polymerase
- C. DNA ligase
- D. Helicase
Explanation
The formation of a new strand of DNA from a template strand is the function of DNA polymerase. DNA polymerase is the enzyme responsible for synthesising the complementary strand of DNA during DNA replication. It adds nucleotides to the growing DNA strand, following the base-pairing rules (A with T and G with C), using the template strand as a guide.

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.
