Question

Assertion (A): PCR is used to detect HIV. 
Reason (R): It is based on the principle of antigen-antibody interaction. 
 

• A. A and R are correct. R is the correct explanation of A
• B. A and R are correct. R is not the correct explanation of A
• C. A is correct but R is incorrect
• D. A is incorrect but R is correct

Hint:

PCR is a technique for amplifying specific DNA sequences, which is different from the principle of antigen-antibody interactions used in immunoassays.

Answer 1

The Correct Option is C

A: The assertion is correct. PCR (Polymerase Chain Reaction) is indeed used to detect HIV by amplifying specific DNA sequences related to the virus.
R: The reason is incorrect because PCR does not rely on antigen-antibody interaction. It amplifies specific DNA sequences using primers, not antigen-antibody interactions.
Final Answer:
A is correct but R is incorrect
