(d) 5 – C Sugar + Nitrogenous base + Phosphoric Acid = Nucleotide
Explanation
A nucleotide is the fundamental unit of nucleic acids such as DNA and RNA. A nucleotide comprises three essential parts: a 5-carbon sugar (pentose), a nitrogenous base, and a phosphoric acid group. All three are necessary for the structure and function of a nucleotide, which participates in carrying genetic information.
