Which of the following products of genetic engineering are not correctly matched with their use ?

Options

A. Tissuse Plasminogen Activator : Breaks blood clot
B. Interferons : Cancer treatment
C. Enzyme DNAse: Helps in cell division and repair of tissues
D. Humulin : To treat insulin dependent diabetes

Answer

To solve the question, we need to identify which of the products of genetic engineering is not correctly matched with its use. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Genetic Engineering**:
- Genetic engineering involves manipulating DNA to alter genetic processes. This can include creating recombinant DNA to produce proteins or modify organisms for various purposes.

2. **Analyzing the Options**:
- We have four pairs to evaluate. We will check if the use described for each product is accurate.

3. **Option 1: Tissue Plasminogen Activator (tPA)**:
- **Use**: Breaks blood clots.
- **Analysis**: tPA is indeed a protein that activates plasminogen to plasmin, which breaks down fibrin in blood clots.
- **Conclusion**: This pair is correctly matched.

4. **Option 2: Interferons**:
- **Use**: Help in cancer treatment.
- **Analysis**: Interferons are proteins released by host cells in response to viral infections and tumors. They help neighboring cells resist viral infections and can also enhance the immune response against tumors.
- **Conclusion**: This pair is correctly matched.

5. **Option 3: Enzyme DNase**:
- **Use**: Helps in cell division and repair of tissue.
- **Analysis**: DNase is an enzyme that cleaves DNA by hydrolyzing phosphodiester bonds. It does not play a direct role in cell division or tissue repair; rather, it is involved in DNA degradation.
- **Conclusion**: This pair is NOT correctly matched.

6. **Option 4: Humulin**:
- **Use**: Used to treat insulin-dependent diabetes.
- **Analysis**: Humulin is a recombinant form of human insulin used to regulate blood glucose levels in diabetic patients.
- **Conclusion**: This pair is correctly matched.

7. **Final Answer**:
- The only incorrect match is **Enzyme DNase**, which does not help in cell division and tissue repair.
