Which is incorrect with respect to GM food?

Options

A. It contains the protein produced by the transgene in question .
B. GM food contains antibiotic resistance gene itself.
C. The enzyme produced by antibiotic resistance gene will not cause allergies.
D. The bacteria in gut of humans could take by antibiotic resistance gene.

Answer

To determine which statement is incorrect with respect to GM (genetically modified) food, let's analyze each option step by step:

1. **Understanding GM Food**: GM food refers to food products that have been genetically modified to enhance certain traits such as resistance to pests, improved nutritional content, or longer shelf life.

2. **Evaluating the Statements**:
- **Statement 1**: "It contains the protein produced by the transgene."
- This statement is **correct**. GM foods often contain proteins that are produced by the transgenes inserted into their genomes. These proteins can provide beneficial traits such as pest resistance.

- **Statement 2**: "GM food contains antibiotic resistance gene itself."
- This statement is also **correct**. Many GM foods have been engineered to include antibiotic resistance genes as markers during the genetic modification process, which helps in identifying successfully modified organisms.

- **Statement 3**: "The enzyme produced by antibiotic resistance gene will not cause allergies."
- This statement is **incorrect**. The enzymes or proteins produced from antibiotic resistance genes can potentially be allergenic or toxic. This is a significant concern in GM food safety assessments, as some individuals may have allergic reactions to these proteins.

- **Statement 4**: "The bacteria in the gut of humans could take up the antibiotic resistance gene."
- This statement is **correct**. There is a possibility that gut bacteria can take up antibiotic resistance genes through horizontal gene transfer, which raises concerns about the spread of antibiotic resistance.

3. **Conclusion**: The incorrect statement regarding GM food is **Statement 3**.

### Final Answer:
The incorrect statement with respect to GM food is: **The enzyme produced by antibiotic resistance gene will not cause allergies.** (Option 3)
