A: ELISA can enable very easy detectron of infection through antigen antibody interaction.
R : It is a nucleic acid based diagonostic tool that can confirm presence of infectious microbe at early stages.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1 )
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
- The assertion states: "ELISA can enable very easy detection of infection through antigen-antibody interaction."
- ELISA stands for Enzyme-Linked Immunosorbent Assay. It is a widely used laboratory technique to detect and quantify proteins, hormones, antibodies, and antigens.
- The method relies on the specific binding of an antigen to its corresponding antibody, which allows for the detection of infections or diseases based on the presence of specific antigens or antibodies in a sample.
- Therefore, the assertion is **true**.

### Step 2: Analyze the Reason
- The reason states: "It is a nucleic acid-based diagnostic tool that can confirm the presence of infectious microbe at early stages."
- This statement is misleading because ELISA is not a nucleic acid-based diagnostic tool; it is based on the interaction of proteins (antigens and antibodies).
- Nucleic acid-based diagnostic tools include techniques like PCR (Polymerase Chain Reaction), which detect the presence of specific DNA or RNA sequences.
- Thus, the reason is **false**.

### Conclusion
- The assertion is true, while the reason is false. Therefore, the correct interpretation of the statements is that the assertion is correct, but the reason is incorrect.

### Final Answer
- Assertion (A) is true, and Reason (R) is false.
