The first transgenic cow , Rosie , Produced human protein - enriched milk. Which of the following year it was produced and what is the human protein produced in the milk ?

Options

A. In 1993 and `beta` - lactamase enzyme
B. In 1997 and `alpha` - lactalbumin protein
C. In 1999 and `alpha-1` - antitrypsin enzyme
D. In 1993 and adenosine deaminase enzyme

Answer

To answer the question regarding the first transgenic cow, Rosie, we need to identify the year she was produced and the specific human protein that was enriched in her milk.

### Step-by-Step Solution:

1. **Identify the Transgenic Cow**: The first transgenic cow is known as Rosie. She was genetically modified to produce milk that contains a specific human protein.

2. **Determine the Year of Production**: Rosie was produced in the year 1997. This is the year when she was created by inserting a gene into her genome.

3. **Identify the Human Protein Produced**: The human protein that Rosie was engineered to produce in her milk is called alpha-lactalbumin. This protein is naturally found in human milk and is important for infant nutrition.

4. **Review the Options**: The options provided were:
- 1993, beta-lactamase enzyme
- 1997, alpha-lactalbumin protein
- 1999, alpha-1 antitrypsin enzyme
- 1993, adenosine deaminase enzyme

5. **Select the Correct Option**: Based on the information, the correct answer is:
- Year: 1997
- Protein: Alpha-lactalbumin

### Final Answer:
The first transgenic cow, Rosie, was produced in **1997**, and the human protein produced in her milk is **alpha-lactalbumin**.
