The bond that exists between N2 bases of DNA is:
Correct answer: B. Hydrogen
- A. Covalent
- B. Hydrogen
- C. Ionic
- D. Phosphodiester
Explanation
Hydrogen bonds are formed between the nitrogenous bases of DNA. Specifically, adenine (A) forms two hydrogen bonds with thymine (T), and guanine (G) forms three hydrogen bonds with cytosine (C). These hydrogen bonds are responsible for holding the two strands of DNA together in the double helix structure.

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.
