Q. In both DNA and RNA, heterocylic base and phosphate ester linkages are at
A) $C_{5}^{'}$ and $C_{1}^{'}$ respectively of the sugar molecule
B) $C_{1}^{'}$ and $C_{5}^{'}$ respectively of the sugar molecule
C) $C_{2}^{'}$ and $C_{5}^{'}$ respectively of the sugar molecule
D) $C_{5}^{'}$ and $C_{2}^{'}$ respectively of the sugar molecule
Explanation
(a)
Synthesis of RNA/DNA from phosphoric acid, ribose and cytosine is given below
Thus ester linkages are at $C_{5}^{''''}\ and\ C_{1}^{''''}$ of sugar molecule.
