The right option is; nucleotides
Nucleotides are the building blocks of DNA macromolecules.
Nucleotides are the building blocks (monomers) that make up a DNA molecule. Each nucleotide that constitutes DNA has three components which are; a five-carbon sugar (ribose or deoxyribose), a nitrogenous base, and a phosphate group. Nucleotides perform several important roles in the cell. They transfer chemical energy to cellular functions that require energy such as in proteins synthesis, and in the movement of the cell. Nucleotides are also involved in cell signaling.
