Nucleotides have a nitrogenous base linked to a sugar by a:
A) α-anhydride bond.
B) β-ester bond.
C) α-N-amide bond.
D) β-N-acetal (glycosidic) bond.
E) α-N-hemiacetal bond.

Question

Quizplus · Accepted Answer

Nucleotides have a nitrogenous base linked to a sugar by a β-N-acetal (glycosidic) bond. This bond forms between the anomeric carbon of the sugar and the nitrogenous base, creating a glycosidic linkage.
