• D. Amino acids

Answer: (C)

Verified step by step guidance

1. Understand that DNA is a type of nucleic acid, which is a macromolecule essential for all known forms of life.
2. Recall that macromolecules are made up of smaller units called monomers. For nucleic acids like DNA, these monomers are known as nucleotides.
3. Nucleotides are composed of three components: a phosphate group, a five-carbon sugar (deoxyribose in DNA), and a nitrogenous base (adenine, thymine, cytosine, or guanine).
4. Differentiate between the types of biological macromolecules: carbohydrates (monosaccharides), lipids (fatty acids), proteins (amino acids), and nucleic acids (nucleotides).
5. Conclude that the monomers of DNA are nucleotides, as they are the building blocks that form the DNA polymer through phosphodiester bonds.
