normal
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
