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 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 the milk produced by Rosie, the transgenic cow, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Transgenic Cow**: Recognize that Rosie is a transgenic cow known for producing milk with specific characteristics due to genetic modifications.

2. **Understand the Key Protein**: The milk produced by Rosie contains human alpha-lactalbumin, a protein that helps regulate lactose levels in the milk. This is a significant feature of the milk.

3. **Evaluate the Milk Composition**: It is noted that the milk produced by Rosie has a higher protein content compared to regular cow milk, making it more suitable for infants. The specific amount of human alpha-lactalbumin in Rosie's milk is approximately 2.4 grams per liter.

4. **Check the Production Year**: The question requires us to identify an incorrect characteristic. It is mentioned that Rosie was the first transgenic cow and that her milk was produced in 1997, not 2001. Therefore, any statement claiming that Rosie's milk was produced in 2001 is incorrect.

5. **Conclude the Answer**: Based on the information, the characteristic that is incorrect is the claim that Rosy's milk was produced for the first time in 2001. The correct answer is option 4.

### Final Answer:
The characteristic that is incorrect about Rosie's milk is that it was produced for the first time in the year 2001. The correct year is 1997.
