Genetically engineered bacteria are being employed for production of

Options

A. Thyroxin
B. Human insulin
C. Cortisol
D. Epinephrine

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which substance is produced by genetically engineered bacteria. The options provided are thyroxine, human insulin, cortisol, and epinephrine.

2. **Identifying the Correct Option**: Among the options, we need to identify which one is known to be produced using genetically engineered bacteria.

3. **Analyzing Each Option**:
- **Thyroxine**: This is a hormone produced by the thyroid gland and is not typically produced by genetically engineered bacteria.
- **Cortisol**: This is a steroid hormone produced by the adrenal glands and is also not produced by genetically engineered bacteria.
- **Epinephrine**: This is another hormone produced by the adrenal glands and is not produced by genetically engineered bacteria.
- **Human Insulin**: This is a hormone that regulates blood sugar levels and is produced by genetically engineered bacteria through biotechnological processes.

4. **Production of Human Insulin**: Human insulin is produced by inserting the human insulin gene into bacteria (commonly E. coli). The bacteria then produce insulin, which can be harvested and purified for medical use.

5. **Conclusion**: Based on the analysis, the correct answer is **human insulin**.

**Final Answer**: Human Insulin
