Question: 1 / 400

Amino acids

Polysaccharides

Nucleotides

The structure of DNA is composed of nucleotides, specifically deoxyribonucleotides. These are made up of a sugar, a phosphate group, and a nitrogenous base. Amino acids are the building blocks of proteins and are not directly involved in the structure of DNA. Polysaccharides are carbohydrates and do not make up the structure of DNA. While proteins do play a role in DNA structure, they are not the primary components.
