Which one is being produced by genetically altered genes

Options

A. Calcitonin
B. Platelet derived growth factor
C. Erythropoietin
D. All the above

Answer

To answer the question "Which one is being produced by genetically altered genes?", we can follow these steps:

### Step 1: Understand the Question
The question asks which substance is produced by genetically altered genes. This implies we are looking for a product of genetic engineering or biotechnology.

### Step 2: Analyze the Options
We have three options to consider:
1. Calcitonin
2. Platelet Derived Growth Factor (PDGF)
3. Erythropoietin

### Step 3: Evaluate Each Option
- **Calcitonin**: This is a hormone produced by the thyroid gland and is not typically produced through genetic engineering.

- **Platelet Derived Growth Factor (PDGF)**: This is a protein that can be synthesized using genetically modified organisms. PDGF is often produced through recombinant DNA technology, making it a product of genetically altered genes.

- **Erythropoietin**: This is a hormone that stimulates the production of red blood cells (RBCs). While it can also be produced using genetic engineering, it is not the primary focus in this context compared to PDGF.

### Step 4: Identify the Correct Answer
Based on the evaluation, the correct answer is **Platelet Derived Growth Factor (PDGF)**, as it is specifically noted for being synthesized by genetically altered genes.

### Conclusion
The substance produced by genetically altered genes is **Platelet Derived Growth Factor (PDGF)**.
