Select the incorrect matched pair

Options

A. Monoclonal antibodies - Hybridomas
B. PCR - Phenylketonuria
C. Bioweapons -Bacillus anthracis
D. Tracy - First transgenic animal for food production

Explanation

To solve the question of selecting the incorrect matched pair, we will analyze each option provided:

### Step-by-Step Solution:

1. **Option A: Monoclonal antibodies, hybridomas**
- Monoclonal antibodies are produced from hybridomas, which are cells formed by the fusion of a specific type of immune cell (B lymphocyte) that produces antibodies and a myeloma (tumor) cell. This option is correctly matched.

2. **Option B: PCR, phenylketonuria**
- PCR (Polymerase Chain Reaction) is a technique used to amplify DNA sequences. It can be used to diagnose genetic disorders, including phenylketonuria (PKU). Therefore, this option is also correctly matched.

3. **Option C: Bioweapon, Bacillus anthracis**
- Bacillus anthracis is the bacterium that causes anthrax and can indeed be used as a bioweapon. This option is correctly matched as well.

4. **Option D: Tracy, first transgenic animal for food production**
- The first transgenic animal created for food production is not Tracy; it is actually a genetically modified salmon. Thus, this option is incorrectly matched.

### Conclusion:
The incorrect matched pair is **Option D: Tracy, first transgenic animal for food production**.
