Question:
Assertion (A): Conjugation is a conservative process.
Reason (R): Donor bacterium generally retain a copy of genetic material as the F plasmid will itself move through the bridge to the recipient cell without replication.
Assertion (A): Conjugation is a conservative process.
Reason (R): Donor bacterium generally retain a copy of genetic material as the F plasmid will itself move through the bridge to the recipient cell without replication.
Show Hint
Conjugation is horizontal gene transfer, not a conservative reproduction method.

- 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 D
Solution and Explanation
Step 1: Concept
Bacterial conjugation mechanisms.
Step 2: Analysis
Conjugation is generally considered a non-conservative (or semi-conservative in replication) process because it facilitates gene transfer. The donor retains the original genetic information but replicates the DNA being transferred. Statement (R) correctly explains the mechanism where a copy is moved, but it contradicts the assertion that the process is "conservative" in the way implied by the options.
Step 3: Conclusion
(A) is considered wrong in standard biological contexts, while (R) correctly describes the transfer mechanism.
Final Answer: (D)
Bacterial conjugation mechanisms.
