Options

A. Protein content of 2.4 g/L
B. Human `alpah`-lactalbumin
C. More balanced diet than normal cow milk for babies
D. Was produced for first time in year 2001

Answer

To solve the question regarding the characteristics of Rosie, the transgenic cow, we need to analyze each option provided and identify which one is not true about the milk produced by Rosie.

### Step-by-Step Solution:

1. **Understand the Concept of Transgenic Cows**:
- Transgenic cows are genetically modified to carry foreign genes that can enhance certain traits, such as milk production or nutritional content.

2. **Identify Rosie the Transgenic Cow**:
- Rosie is known as the first transgenic cow, created in 1997, and is specifically modified to produce milk with enhanced nutritional properties.

3. **Evaluate the Given Options**:
- **Option 1**: Protein content of 2.4 grams per liter.
- This is a characteristic of Rosie’s milk, as it is higher in protein compared to regular cow milk. This option is true.

- **Option 2**: Contains human alpha-lactoalbumin.
- Rosie’s milk does indeed contain this protein, which is a result of the transgenic modification. This option is also true.

- **Option 3**: More balanced diet than normal cow milk for babies.
- The milk from Rosie is designed to be more suitable for infants, making this statement true as well.

- **Option 4**: Was produced for the first time in the year 2001.
- This statement is incorrect because Rosie was actually produced in 1997. Therefore, this is the exception.

4. **Conclusion**:
- The correct answer to the question is that Rosie’s milk was not produced for the first time in 2001; it was produced in 1997.

### Final Answer:
The characteristic that is NOT true about Rosie’s milk is: "Was produced for the first time in the year 2001."
