Updated On: Jun 26, 2026
- uracil
- adenine
- guanine
- thymine
- cytosine
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Identify the nitrogenous bases found in nucleic acids.
Step 2: Meaning
DNA contains Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).
Step 3: Analysis
RNA contains Uracil (U) instead of Thymine.
Step 4: Conclusion
Uracil is present in RNA but not in DNA. Final Answer: (A)
