Nucleotides are referred to as subunits of DNA because they are the fundamental building blocks that make up the larger structure of the DNA molecule. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base, and when linked together, they form the long chains that create the DNA double helix. The term "subunit" emphasizes their role as individual components that combine to form the complete DNA structure, similar to how smaller parts contribute to a whole system.
