- Both (A) and (R) are true. (R) is the correct explanation for (A)
- Both (A) and (R) are true. (R) is not the correct explanation for (A)
- (A) is true. But (R) is false
- (A) is false. But (R) is true
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Tumor suppressor genes.
Step 2: Analysis
Assertion (A) is true: The p53 gene is nicknamed the "guardian angel of the genome" due to its role in DNA repair and apoptosis. Reason (R) is true: It functions as a tumor suppressor by inhibiting uncontrolled cell growth, directly explaining why it protects the genome.
Step 3: Conclusion
Both are true, and (R) is the explanation.
Final Answer: (A)
Tumor suppressor genes.
Step 2: Analysis
