Vedclass · Answer

(D) In $DNA$,the nitrogenous base is attached to the pentose sugar via an $N$-glycosidic linkage.For purines (Adenine and Guanine),the linkage is between the $C-1^{\prime}$ of the sugar and the $N-9$ position of the base,known as a $\beta-1^{\prime}-9-N$-glycosidic bond.For pyrimidines (Cytosine and Thymine),the linkage is between the $C-1^{\prime}$ of the sugar and the $N-1$ position of the base,known as a $\beta-1^{\prime}-1-N$-glycosidic bond.The nucleotides are linked together by $3^{\prime}-5^{\prime}$ phosphodiester bonds.Therefore,a $\beta-1^{\prime}-2-N$-glycosidic bond is not present in $DNA$.
