Which of the following bond is not present in $DNA$?

A

$\beta-1^{\prime}-9-N-g$ lycosidic bond

B

$3^{\prime}-5^{\prime}$ phosphodiester bond

C

$\beta-1^{\prime}-1- N - glycosidic$ bond

D

$\beta-1^{\prime}-2-N$-glycosidic bond

Solution

$\beta-1^{\prime}-9^{\prime} \rightarrow$ Glycosidic bond $\rightarrow$ Sugar and Purines

$\beta-1^{\prime}-1^{\prime} \rightarrow$ Glycosidic bond $\rightarrow$ Sugar and Pyrimidine

3' $-5^{\prime} \rightarrow$ Phosphodiester bond $\rightarrow$ Sugar and Phosphate
