What is the basic unit that composes DNA?

Explanation:
DNA is a polymer built from nucleotides, the basic building blocks of nucleic acids. Each nucleotide includes a deoxyribose sugar, a phosphate group, and a nitrogenous base; long chains are formed by sugar–phosphate linkages, with the bases projecting inward to pair A with T and G with C, giving the double-helix structure and storing genetic information in the sequence. Lipids, proteins, and monosaccharides are units of other biomolecules (membranes, enzymes, and carbohydrates, respectively), but they are not the monomers that compose DNA.
