Which of the following is drug produced by genetic engineering and is used in the treatment of cancer ?

Options

A. Alpha- interferon
B. Human growth hormone
C. Insulin
D. Calcitonin

Answer

To determine which drug produced by genetic engineering is used in the treatment of cancer, we can analyze the options provided:

1. **Terpiron**: This is not a well-known drug associated with cancer treatment or genetic engineering.

2. **Human Growth Hormone (HGH)**: This hormone is produced by the pituitary gland and is primarily involved in growth and development. It is not used for cancer treatment.

3. **Insulin**: Insulin is a hormone that regulates blood sugar levels and is used in the management of diabetes. It is not related to cancer treatment.

4. **Calcitonin**: This hormone is involved in calcium regulation in the body and is not used for cancer treatment.

Now, we can consider the role of **alpha interferon**, which is a type of interferon that is produced using genetic engineering. Alpha interferon is known for its ability to stimulate the immune system to fight against cancer cells. It helps enhance the immune response, encouraging T cells and other immune cells to attack cancer cells.

Based on this analysis, the correct answer to the question is:

**Alpha Interferon** (though it was not listed in the options, it is the drug produced by genetic engineering that is used in cancer treatment).

However, if we strictly adhere to the options given, none of them are correct in the context of being a drug produced by genetic engineering specifically for cancer treatment.

### Step-by-Step Solution:
1. **Identify the options**: The options provided are Terpiron, Human Growth Hormone, Insulin, and Calcitonin.

2. **Analyze each option**:
- Terpiron: Not related to cancer treatment.
- Human Growth Hormone: Related to growth, not cancer.
- Insulin: Related to blood sugar control, not cancer.
- Calcitonin: Related to calcium regulation, not cancer.

3. **Consider the role of genetic engineering in drug production**: Recognize that some drugs used in cancer treatment are produced through genetic engineering, such as alpha interferon.

4. **Conclusion**: None of the options provided are correct for the question asked. The drug produced by genetic engineering that is used in cancer treatment is alpha interferon.
