Q. RNA and DNA are chiral molecules, their chirality is due to
A) chiral bases
B) chiral phosphate ester units
C) D-sugar component
D) L-sugar component
Explanation
[Solution from source] The bases and phosphate groups are achiral; the chirality of DNA and RNA comes from the D-ribose/D-deoxyribose sugars. Natural nucleic acids contain D-, not L-, sugars. Answer (3).
