Which genes encode the protein to control bollworms infection in cotton plants?

Options

A. Cry II Ab
B. Cry I Ac
C. Both (1) and (2)
D. `Amp^(r)`

Answer

To answer the question regarding which genes encode the protein to control bollworm infection in cotton plants, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Problem**: The question asks for the specific genes responsible for controlling bollworm infection in cotton plants.

2. **Understand the Context**: Cotton plants can be genetically modified to resist pests, particularly the cotton bollworm, which is a significant threat to cotton crops.

3. **Research the Relevant Genes**: The two primary genes known for providing resistance to bollworms in cotton are:
- **Cry1AC**
- **Cry2AB**

4. **Explain the Function of These Genes**:
- These genes encode proteins that produce a toxin known as **Bt toxin**.
- This toxin is derived from the bacterium **Bacillus thuringiensis**.

5. **Mechanism of Action**:
- When bollworms consume the cotton plant containing these genes, the Bt toxin interacts with the insect's gut, leading to cell lysis (destruction of gut cells), which ultimately kills the insect.

6. **Conclusion**: Therefore, the genes that encode the proteins to control bollworm infection in cotton plants are **Cry1AC and Cry2AB**.

7. **Final Answer**: The correct answer to the question is that both **Cry1AC and Cry2AB** genes are responsible for controlling bollworm infection in cotton plants.
