उत्तर
A nucleotide consists of three chemically distinct components: a nitrogenous base (purine or pyrimidine), a pentose sugar (ribose in RNA or deoxyribose in DNA), and a phosphate group derived from phosphoric acid. These three components link together to form the basic monomeric unit of nucleic acids.
