Which G.M. plant produces protein hirudin

Options

A. Brassica oleracea
B. Brassica rapa
C. Brassica napus
D. Brassica campestris.

Answer

To determine which genetically modified (G.M.) plant produces the protein hirudin, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hirudin**: Hirudin is a protein that acts as a powerful anticoagulant. It is primarily known for its ability to inhibit thrombin, an enzyme involved in blood clotting.

2. **Identify the Options**: The options provided are:
- Option 1: Brassica oleracea
- Option 2: Brassica rapa
- Option 3: Brassica napus
- Option 4: Brassica campestris

3. **Research on G.M. Plants**: We need to identify if any of these Brassica species have been genetically modified to produce hirudin.

4. **Focus on Brassica napus**: Among the options, Brassica napus is known to be genetically modified to produce hirudin. This plant has been engineered to express the hirudin gene, allowing it to produce the protein.

5. **Conclusion**: Based on the information gathered, the correct answer is **Option 3: Brassica napus**.

### Final Answer:
The G.M. plant that produces the protein hirudin is **Brassica napus**.
