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. **Understanding Genetic Engineering**: The process of making Bt cotton involves genetic engineering, which allows scientists to manipulate the genetic material of organisms. This means that desirable genes can be incorporated into the DNA of the cotton plants.

3. **Mechanism of Resistance**: The Bt bacterium produces a toxic insecticidal protein in the form of crystals. When these genes (Cry1AC and Cry2AB) are inserted into the cotton plant's genome, the plant gains the ability to produce these insecticidal crystals.
