The first human drug made using recombinant DNA technology was-

Options

A. Glyphosatase
B. TPA
C. Insulin
D. Erythropoietin

Answer

**Step-by-Step Solution:**

1. **Understanding Recombinant DNA Technology**:
- Recombinant DNA technology involves combining DNA from different sources to create new genetic combinations. This technology allows for the production of proteins that can be used as drugs.

2. **Identifying the First Human Drug**:
- The question asks for the first human drug produced using this technology. Among the options given: glyphosate, tPA, insulin, and erythropoietin, we need to determine which one was the first.

3. **Researching the Options**:
- **Glyphosate**: This is a herbicide and not a human drug.
- **tPA (tissue Plasminogen Activator)**: This is a drug used for treating strokes but was not the first.
- **Insulin**: Human insulin was the first drug produced using recombinant DNA technology in 1982.
- **Erythropoietin**: This is a hormone that stimulates red blood cell production but was developed after insulin.

4. **Conclusion**:
- Based on the historical timeline and the applications of recombinant DNA technology, the first human drug made using this technology is **Insulin**.

**Final Answer**: The first human drug made using recombinant DNA technology was **Insulin**.
