Vedclass · Answer

(C) In a nucleoside,the nitrogenous base is linked to the $C1'$ position of the sugar (ribose or deoxyribose) via a $\beta$-glycosidic linkage. For purine bases (like adenine or guanine),this linkage occurs at the $N9$ nitrogen atom. For pyrimidine bases (like cytosine,thymine,or uracil),this linkage occurs at the $N1$ nitrogen atom. As shown in the provided structure,the furanose ring is attached to the $N9$ position of the purine base.

Which nitrogen atom of a purine base is bonded with the furanose sugar to form a nucleoside?
