Answer:
C. Nucleotides
Explanation:
DNA are made up of three components of monomers called nucelotides. These nucleotides are made up of a deoxyribose sugar, a phosphate group and nitrogenous bases. The nitrogenous bases are adenine, guanine, cytosine, thymine. Uracil which is also a nitrogenous base is only found in RNA and not DNAs. A 5 carbon deoxyribose sugar attached to a phosphate group and nitrogenous bases which interact with each other through bonding. The nitrogenous bases adenine binds with thymine with double bonds while cytosine binds with guanine with triple bonds.
