Which of the following is not the application of transgenic animals ?

Options

A. Developing animals specially created for use in xenografting
B. Molecular diagnosis of pathogens such as detecting presence of antiques their protein or glycoproteins, etc.
C. To test genetically engineered hormones to increase milk ,meat production , etc .
D. To rest pharmaceutical proteins, drugs production etc.

Answer

To solve the question "Which of the following is not the application of transgenic animals?", we will analyze each option provided in the question step by step.

### Step 1: Understand Transgenic Animals
Transgenic animals are organisms that have had a foreign gene deliberately inserted into their genome. This technology is used for various applications, including medical research, agriculture, and pharmaceuticals.

### Step 2: Evaluate Each Option
1. **Developing animals specially created for the use in Xenografting**:
- This is indeed an application of transgenic animals. Xenografting involves using tissues from one species in another, and transgenic animals can be engineered to have compatible tissues for this purpose.

2. **Molecular diagnosis of pathogens such as detecting presence of the antigens, their proteins, or glycoproteins**:
- This is NOT an application of transgenic animals. Molecular diagnosis typically involves techniques like PCR or ELISA, which do not require transgenic animals.

3. **To test genetically engineered hormones to increase milk production**:
- This is an application of transgenic animals. Genes can be inserted into animals to enhance milk production, making this a valid application.

4. **To test pharmaceutical proteins, drugs, production, etc.**:
- This is also an application of transgenic animals. They can be used to produce proteins that are used in pharmaceuticals.

### Step 3: Identify the Correct Answer
After evaluating all the options, the option that is NOT an application of transgenic animals is the second one: **Molecular diagnosis of pathogens such as detecting presence of the antigens, their proteins, or glycoproteins.**

### Final Answer
The correct answer is **Option 2**.
