C. nucleotides
Explanation
DNA, or deoxyribonucleic acid, is made up of nucleotide units. These nucleotides consist of a sugar, a phosphate group, and a nitrogenous base. DNA strands are formed by phosphodiester bonds between these repeating nucleotide units. Polysaccharides, fatty acids, and amino acids are not involved in forming the structure of DNA.
