Answer to the Multiple Choice Question

Nucleotides are the subunits of nucleic acids.

Explanation

Nucleotides play a critical role in the structure and function of nucleic acids, which include DNA and RNA. Each nucleotide is composed of three components: a nitrogenous base (which can be adenine, thymine, cytosine, guanine in DNA, and uracil in RNA), a five-carbon sugar (deoxyribose in DNA and ribose in RNA), and a phosphate group. These nucleotides link together through phosphodiester bonds to form long chains, creating the backbone of nucleic acids. Proteins, carbohydrates, and lipids are formed from different types of subunits (amino acids, monosaccharides, and fatty acids, respectively) and do not contain nucleotides as their building blocks. Thus, the correct answer is nucleic acids, specifically highlighting their role in genetic information storage and transfer.
