Biolistics (gene-gun) is suitable for

Options

A. Constructing recombinant DNA by joining with vector
B. DNA finger printing
C. Disarming pathogen vectors
D. Transformation of plants cells

Answer

**Step-by-Step Solution:**

1. **Understanding Biolistics (Gene Gun):**
- Biolistics, commonly referred to as the gene gun method, is a technique used to introduce foreign DNA into cells. It involves shooting microscopic gold or tungsten particles coated with DNA into target cells.

2. **Identifying Suitable Applications:**
- The question asks for the suitable application of the biolistics method. We need to evaluate the provided options to determine which one aligns with the capabilities of the gene gun.

3. **Evaluating the Options:**
- **Option 1:** Constructing recombinant DNA by joining vectors.
- This is typically done through molecular cloning techniques, not directly through biolistics. Therefore, this option is not suitable.

- **Option 2:** DNA fingerprinting to identify matches or repetitive sequences.
- DNA fingerprinting is a method used for identifying genetic relationships and is not related to the gene gun technique. Hence, this option is also not suitable.

- **Option 3:** Disarming pathogen vectors.
- Disarming pathogen vectors is not a direct application of the gene gun method. This option does not fit the purpose of biolistics.

- **Option 4:** Transformation of plant cells.
- The gene gun method is specifically designed for the transformation of plant cells. It allows for the direct introduction of DNA into the nucleus of plant cells, making it suitable for creating genetically modified plants.

4. **Conclusion:**
- Based on the evaluation, the correct answer is that biolistics (gene gun) is suitable for the transformation of plant cells.

**Final Answer:**
Biolistics (gene gun) is suitable for the transformation of plant cells.
