The transgenic cow named Rosie produced milk enriched with human protein alpha lactalbumin of about

Options

A. 1.4g/litre
B. 2.4 g/litre
C. 4.2 g/litre
D. 4.1 g/litre

Answer

To solve the question regarding the transgenic cow named Rosie and the amount of human protein alpha-lactalbumin in her milk, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Transgenic Animals**:
- Transgenic animals are those that have had a foreign gene deliberately inserted into their genome. In this case, Rosie is a transgenic cow that produces milk enriched with a human protein.

2. **Identify the Protein Produced**:
- The specific human protein mentioned is alpha-lactalbumin, which is known for its nutritional value and digestibility, especially for infants and older adults.

3. **Determine the Amount of Protein in Milk**:
- The question asks for the amount of alpha-lactalbumin produced in Rosie’s milk. The options provided are:
- 1.4 grams per liter
- 2.4 grams per liter
- 4.2 grams per liter
- 4.1 grams per liter

4. **Recall the Information about Rosie**:
- Rosie was the first genetically modified cow, developed in 1997, and was known for producing milk that contained a significant amount of alpha-lactalbumin.

5. **Select the Correct Option**:
- Based on the information provided in the video transcript, Rosie produced milk enriched with alpha-lactalbumin at a concentration of **2.4 grams per liter**.

6. **Final Answer**:
- Therefore, the correct answer is **2.4 grams per liter**.
