Concerning the precise structural formation and nomenclature of nucleosides and nucleotides, which o — Biomolecules Chemistry Question

💡 Solution & Explanation

A nucleoside comprises just the sugar and base via an $N$ -glycosidic bond (at $N-1$ for pyrimidines, $N-9$ for purines). Adding a phosphate group forms a nucleotide. Nucleotides are polymerized into nucleic acids via phosphodiester linkages, never via peptide bonds.
