Rosie' a transgenic cow is known to produce a type of milk which has all the following charcteristics, except

Options

A. Protein content of 2 .4 gm/litre
B. has human ` alpha ` - lactalbumin
C. more balanced dit than normal cow milk for babies
D. was produced for the first time in year 2001

Answer

To solve the question regarding the characteristics of the transgenic cow 'Rosie' and the type of milk she produces, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Transgenic Cows**:
- Transgenic cows like Rosie are genetically modified to produce milk with enhanced nutritional properties. This often includes the production of specific proteins that are beneficial for human consumption.

2. **Analyzing Option A**:
- **Option A** states that the milk has a protein content of 2.4 grams per liter.
- This is a plausible characteristic for Rosie’s milk, as transgenic modifications often increase protein content.

3. **Analyzing Option B**:
- **Option B** mentions that the milk contains human alpha-lactalbumin.
- Alpha-lactalbumin is a protein that is significant for lactose regulation in milk and is indeed produced in Rosie’s milk, making this statement correct.

4. **Analyzing Option C**:
- **Option C** claims that the milk provides a more balanced diet than normal cow milk for babies.
- Given that Rosie’s milk has enhanced protein content, it is reasonable to conclude that it would be more beneficial for infants, thus this statement is also correct.

5. **Analyzing Option D**:
- **Option D** states that Rosie was produced for the first time in the year 2001.
- However, according to the information provided, Rosie was actually produced in 1997. Therefore, this statement is incorrect.

6. **Conclusion**:
- Since the question asks for the characteristic that is NOT true about Rosie’s milk, the answer is **Option D**: "was produced for the first time in the year 2001."

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