Name the genes responsible for making Bt cotton plants resistant to bollworm attack. How do such plants attain resistance against bollworm attacks? Explain.

Explanation

### Step-by-Step Solution:

1. **Identify the Genes**: The genes responsible for making Bt cotton plants resistant to bollworm attacks are **CRY1AC** and **CRY2AB**. These genes are derived from the bacterium *Bacillus thuringiensis* (Bt).

2. **Mechanism of Resistance**:
- **Production of Bt Toxin**: The genes CRY1AC and CRY2AB encode for proteins that produce a toxin known as the Bt toxin. This toxin is initially inactive when produced by the bacterium.

3. **Activation of the Toxin**:
