A) hydrogen bond
B) glycosidic bond
C) phosphate diester bond
D) peptide bond
Correct Answer: B
Solution :
A nitrogenous base is linked to the pentose sugar through a N-glycosidic linkage to form a nucleoside, such as aderaosine or deoxyadenosine, etc. When a phosphate group is linked to \[{{5}^{1}}\]?OH of a nucleoside through phosphoester linkage, a corresponding nucleotide is formed. Two nucleotides are linked through 3-5 phosphodiester linkage to form a dinucleotide.
