Vedclass · Answer

(B) The sugar present in $RNA$ is ribose,while the sugar present in $DNA$ is $2'$-deoxyribose.In $\beta$-$D$-ribose (found in $RNA$),there is a hydroxyl $(-OH)$ group attached to the $2^{	ext{nd}}$ carbon atom.In $\beta$-$D$-deoxyribose (found in $DNA$),the hydroxyl group is absent at the $2^{	ext{nd}}$ carbon atom,and only a hydrogen atom is present.Therefore,the presence or absence of the hydroxyl group at the $2^{	ext{nd}}$ carbon atom differentiates $RNA$ and $DNA$.

The presence or absence of hydroxyl group on which carbon atom of sugar differentiates $RNA$ and $DNA$?
