RNA and DNA are chiral molecules, their chirality is due to (AIPMT 2007)
A.L-sugar component
B.chiral bases
C.chiral phosphate ester units
D.D-sugar component✓ Correct
Explanation
RNA stands for ribonucleic acid and DNA stands for Deoxyribose nucleic acid which suggests that RNA has ribose sugar whereas DNA has deoxyribose sugar. Both of them are chiral and their chirality arises due to the D-ribose or deoxyribose sugar components. Thus, the correct option is (d) D-sugar component
