Rosie was a :

Options

A. Transgenic animal
B. Cloned animal
C. Transgenic prokaryote
D. All of these

Answer

**Step-by-Step Solution:**

1. **Identify the Subject**: The question is asking about "Rosie." We need to determine what Rosie is in the context of biotechnology.

2. **Define Rosie**: Rosie is identified as a transgenic cow. This means that she has been genetically modified to express certain traits that are not found in normal cows.

3. **Explain Transgenic Characteristics**: Transgenic cows are different from normal cows because they can produce specific proteins or substances that are beneficial. In Rosie's case, she produces milk that is enriched with human proteins.

4. **Specific Protein in Rosie's Milk**: The milk produced by Rosie contains human alpha-lactalbumin, which is a protein that is important for human nutrition, especially for infants.

5. **Nutritional Benefits**: The milk from Rosie is described as being more nutritionally balanced for human babies compared to normal cow milk, making it a better option for infant nutrition.

6. **Conclusion**: Therefore, Rosie can be classified as a transgenic animal, specifically a transgenic cow that produces human protein-enriched milk.

**Final Answer**: Rosie was a transgenic cow.
