Question

PCR is NOT used in ______.

• A. lytic cycle
• B. DNA fingerprinting
• C. DNA cloning
• D. gene amplification

Hint:

PCR is a laboratory technique, not a biological life cycle process.

Answer 1

The Correct Option is A

Step 1: Understanding PCR.
PCR (Polymerase Chain Reaction) is a technique used to amplify DNA segments in vitro.
Step 2: Analyzing the options.
(A) lytic cycle: Correct. PCR is not involved in the viral lytic cycle.
(B) DNA fingerprinting: Incorrect. PCR is widely used in DNA fingerprinting.
(C) DNA cloning: Incorrect. PCR helps in amplifying DNA before cloning.
(D) gene amplification: Incorrect. PCR itself is a method of gene amplification.
Step 3: Conclusion.
The correct answer is (A) lytic cycle.
