Question:
Assertion (A): The genetic material should be stable enough not to change with different stages of life cycle, age, with change in physiology of organism.
Reason (R): stability of genetic material is clearly evidenced with transforming principle.
Assertion (A): The genetic material should be stable enough not to change with different stages of life cycle, age, with change in physiology of organism.
Reason (R): stability of genetic material is clearly evidenced with transforming principle.
Show Hint
DNA must be stable to remain constant through time and change!

- Both (A) and (R) are correct and (R) is the correct explanation to (A)
- Both (A) and (R) are correct but (R) is not correct explanation for (A)
- (A) is correct (R) is wrong
- (A) is wrong (R) is correct
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Criteria for genetic material stability.
Step 2: Meaning
Assessing scientific assertions about DNA stability and experimental evidence.
Step 3: Analysis
Assertion (A) is a fundamental criterion for genetic material to ensure continuity across generations. Reason (R) correctly identifies that the transforming principle (Griffith's experiment) demonstrated the stability of genetic material despite physiological changes in bacteria; however, it does not explain *why* stability is required for life stages.
Step 4: Conclusion
Both are true, but the reason does not explain the assertion.
Final Answer: (B)
