In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called

a. carbohydrates

b. ribosomes

c. nucelotides

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.
