For nucleotides, which bond links nitrogenous bases to a sugar:
A. a-N-hemiacetal bond
OB. B-ester bond
OC. a-N-amide bond
OD. B-N-acetal (glycosidic) bond
E. a-anhydride bond



Answer :

Final answer:

The N-glycosidic bond links nitrogenous bases to a sugar in nucleotides, crucial for DNA and RNA structure.


Explanation:

The bond that links nitrogenous bases to a sugar in nucleotides is called N-glycosidic bond. This bond forms when the secondary amine nitrogen of a base reacts with the anomeric carbon of a deoxyribose. It is essential for connecting the nitrogenous bases (G, C, A, T, or U) to the sugar in nucleotides.
