Nucleotides contain sugar, a phosphate group, and a nitrogen base. Which of the following is a nitrogen base? (1 point)

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine. Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and a nitrogenous base. The nucleic acids are of two major types: natural and synthetic nucleic acids. They contain a sugar phosphate and nitrogen base.
