Answer:

G. Nitrogenous base

Explanation:

Double-stranded DNA (Deoxyribonuclease) molecules store genetic information. Their 5-carbon deoxyribose sugar, phosphate and one of four nitrogenous bases from which nucleotides derive their name:

  • Adenine (A)
  • Guanine (G)
  • Cytosine (C)
  • Thymine (T).

The nucleotides on a single strand are bonded together via covalent bonding. Base pairs are formed between nucleotides on opposite strands, due to hydrogen bonding between bases. For instance, Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.
