Question

Name the most abundant elements which occur in nucleic acid macromolecules

• A. $C,H,O,N,S$
• B. $C,O,N,S$
• C. $C,O,P,S$
• D. $C,H,O,N,P$
• E. $H,O,P$

Answer 1

The correct option is D $C,H,O,N,P$

Nucleic acids consists nucleotides made of of nitrogenous base, sugar and phosphate. The nitrogenous bases are purines and pyrimidines. The purines are adenine and guanine. The pyrimidines are thymine, uracil and cytosine. The purines are double ring structure while the pyrimidines are single ring made up of carbon hydrogen oxygen and nitrogen. Ribose and deoxyribose sugars are the cyclic rings of carbon, hydrogen and oxygen.

So, the correct answer is option D.
