DNA is made of?

Explanation:
DNA is made of nucleotides. Each nucleotide contains a sugar (deoxyribose), a phosphate group, and a nitrogenous base. The sugar and phosphate form the continuous backbone of the molecule, while the bases extend inward and pair (A with T, C with G) to create the double helix. The sequence of these bases stores genetic information used to direct protein production and cellular function. Amino acids are the building blocks of proteins, not DNA itself; sugars describe types of carbohydrates, and fatty acids are components of lipids.
