Question:
Assertion (A): PCR is used to detect HIV.
Reason (R): It is based on the principle of antigen-antibody interaction.
Assertion (A): PCR is used to detect HIV.
Reason (R): It is based on the principle of antigen-antibody interaction.
Show Hint
PCR is a technique for amplifying specific DNA sequences, which is different from the principle of antigen-antibody interactions used in immunoassays.

- A and R are correct. R is the correct explanation of A
- A and R are correct. R is not the correct explanation of A
- A is correct but R is incorrect
- A is incorrect but R is correct
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
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
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

Top Questions on Genetics
If a heterozygous tall plant (Tt) is crossed with a dwarf plant (tt), what will be the phenotypic ratio of the offspring?
- Assertion (A): When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than non-parental type.
Reason (R): Higher parental gene combinations can be attributed to crossing over between two genes. Study the cross given below:
Identify the abnormalities ‘1’ and ‘2’ in the offsprings of a cross done between a couple and distinguish between them.- Assertion (A): One of the properties of genetic code is degeneracy.
Reason (R): Some amino acids can be coded by more than one codon. - Assertion (A): A bioreactor provides the optimal conditions for achieving the desired product by providing optimum growth conditions.
Reason (R): The most commonly used bioreactors are of stirring type.
