Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Biomolecules are chemical compounds present in living organisms.
DNA stands for:
\[
\text{Deoxyribonucleic Acid}
\]
It carries hereditary information from one generation to another.
Step 1: Understand the role of DNA. DNA contains genes responsible for inheritance and expression of characters. It stores biological information in the sequence of nitrogenous bases.
Step 2: Analyze other biomolecules.
Step 3: Conclusion. Hence DNA acts as genetic material in most organisms. \[ \boxed{\text{DNA}} \]
Step 1: Understand the role of DNA. DNA contains genes responsible for inheritance and expression of characters. It stores biological information in the sequence of nitrogenous bases.
Step 2: Analyze other biomolecules.
- Proteins mainly perform structural and enzymatic functions.
- Lipids store energy and form membranes.
- Polysaccharides mainly act as energy reserves.
Step 3: Conclusion. Hence DNA acts as genetic material in most organisms. \[ \boxed{\text{DNA}} \]
