Which method of diagnosis is used for detecting mutations quicker than other method?

Options

A. PCR
B. ELISA
C. Western blotting
D. ESR

Answer

To answer the question regarding which method of diagnosis is used for detecting mutations quicker than other methods, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the method of diagnosis that allows for the quick detection of mutations. Mutations refer to sudden changes in genes.

2. **Evaluating the Options**:
- **Option 1: PCR (Polymerase Chain Reaction)**: This method is known for amplifying small amounts of nucleic acid, which allows for the early detection of mutations. PCR can detect mutations quickly due to its ability to amplify DNA, making it a strong candidate for the correct answer.

- **Option 2: ELISA (Enzyme-Linked Immunosorbent Assay)**: This method is primarily used for detecting proteins through antigen-antibody interactions. It is not designed for detecting mutations in DNA, making it an unsuitable choice for this question.

- **Option 3: Western Blotting**: This technique is used to confirm the results of ELISA tests by detecting specific proteins. It does not detect mutations in DNA, so it is not the correct answer.

- **Option 4: ESR (Erythrocyte Sedimentation Rate)**: This test measures inflammation in the body and does not relate to the detection of mutations. Therefore, it is also not the right answer.

3. **Conclusion**: After evaluating all the options, it is clear that PCR (Polymerase Chain Reaction) is the method that allows for the quickest detection of mutations compared to the other methods listed.

### Final Answer:
The method of diagnosis used for detecting mutations quicker than other methods is **PCR (Polymerase Chain Reaction)**.
