Nucleosidesand nucleotides arise from substitutions on the ring structures of the parent bases. Anucleosideis formed from an oxygen–nitrogenglycosidic linkageof a pentose to anitrogenous base. The pentose can be either D-ribose as in ribonucleic acid (RNA) or 2-deoxyribose as in deoxyribonucleic ...
