$1^{\prime} C$ pentose sugar

Vedclass · Answer

(A) The correct answer is option $A$ because,in the polynucleotide chain of $DNA$,a nitrogenous base is linked to the $1^{\prime} C$ of the pentose sugar via an $N$-glycosidic linkage.Option $B$ is incorrect as the $2^{\prime} C$ of the pentose sugar in $DNA$ contains a hydrogen atom $(-H)$,whereas in $RNA$,it contains a hydroxyl group $(-OH)$.Options $C$ and $D$ are incorrect because the $3^{\prime} C$ and $5^{\prime} C$ of the pentose sugar are involved in the formation of the phosphodiester bond that links adjacent nucleotides in the polynucleotide chain.
