Select the wrong statement:

Options

A. Human insulin is being commerically produced from a transgenice species of Escherichia coli
B. Genetically modified Bacillus thuringiensis is used as biopesticide on commercial scale
C. Human protein,`alpha`-1 antitypsin, is used to treqat emphysema
D. Bt toxin genes cry Iac control corn brer

Answer

To solve the question, we need to analyze each statement provided in the options and determine which one is incorrect.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Human insulin is being commercially produced from transgenic E. coli."
- This statement is **correct**. E. coli is genetically modified to produce human insulin, known as Humulin.

2. **Statement Analysis**:
- **Statement 2**: "Genetically modified Bacillus thuringiensis is used as biopesticides on a commercial scale."
- This statement is **correct**. Bacillus thuringiensis (Bt) produces a protein that is used as a biopesticide to control various insect pests.

3. **Statement Analysis**:
- **Statement 3**: "Human protein alpha-antitrypsin is used in the treatment of emphysema."
- This statement is **correct**. Alpha-antitrypsin is a protein that helps protect the lungs and is used in treating emphysema, a lung disease.

4. **Statement Analysis**:
- **Statement 4**: "Bt toxin genes cryIAC control corn borer."
- This statement is **incorrect**. The cryIAC gene is actually used to control the cotton bollworm, while the cryIAB gene is used for corn borer control. Therefore, this statement misidentifies the target pest for the cryIAC gene.

### Conclusion:
The wrong statement is: **"Bt toxin genes cryIAC control corn borer."**
