Select the incorrect match .

Options

A. `{:("Column A","Colum B"),("Taq polymerase ","Annealing of DNA"):}`
B. `{:("Column A","Colum B"),("Chitinase ","Obtaining DNA by lysis of fungal cell"):}`
C. `{:("Column A","Colum B"),("Exonucleases ","Remove mucleotides from the ends of DNA"):}`
D. `{:("Column A","Colum B"),("DNA ligase ","Joining the fragments of DNA"):}`

Answer

To solve the question, we need to analyze the matches between the enzymes listed in Column A and their respective roles in Column B. We will go through each enzyme and its function to identify the incorrect match.

### Step-by-Step Solution:

1. **Identify the Enzymes and Their Functions**:
- **Taq Polymerase**: This enzyme is used in the Polymerase Chain Reaction (PCR) to amplify DNA. It synthesizes new DNA strands by adding nucleotides to the primers.
- **Chitinase**: This enzyme is involved in breaking down chitin, which is a component of fungal cell walls. It is used to lyse fungal cells to obtain DNA.
- **Exonucleases**: These enzymes remove nucleotides from the ends of DNA strands. They play a role in DNA repair and processing.
- **DNA Ligases**: These enzymes are responsible for joining DNA fragments together, particularly during DNA replication and repair.

2. **Evaluate Each Match**:
- **Taq Polymerase**: Correctly matched with its role in PCR.
- **Chitinase**: Correctly matched with its role in lysing fungal cell walls.
- **Exonucleases**: Correctly matched with their role in removing nucleotides from DNA ends.
- **DNA Ligases**: Correctly matched with their role in joining DNA fragments.

3. **Conclusion**:
- Since all the matches for Taq Polymerase, Chitinase, Exonucleases, and DNA Ligases are correct, we need to identify which one is incorrectly matched. The question states that the incorrect match is the first option, which is Taq Polymerase. However, the role of Taq Polymerase is indeed correct, suggesting that the question may have a misunderstanding or mislabeling.

### Final Answer:
The incorrect match is **Taq Polymerase**, as it is incorrectly labeled in the context of the question.
