In the carbon skeleton of the pentose sugar in DNA, what is the attachment point of a base to form a nucleoside ?

A

`C_(3)`

B

`C_(2)`

C

`C_(1)`

D

`C_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Deoxyribose is the sugar found in the backbone of DNA. `C_(1)` of this sugar is linked to the `N_(1)` of a pyrimidine or the `N_(9)` of a purine base by a `beta -N-` glycosidic linkage.
