Which nucleic acid component consists of a nitrogenous base, a pentose sugar, and at least one phosphate group?

💡 Solution & Explanation

A nucleotide comprises a nitrogenous base, a pentose sugar, and one or more phosphate groups, serving as the repeating monomer unit of nucleic acids like DNA and RNA. A nucleoside lacks the phosphate group entirely. Fundamental biochemical definitions are frequently featured in competitive biology questions.
