Creative technique involving repairing or replacement of defective genes is

Options

A. Gene therapy
B. Genetic recombination
C. Gene cloning
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for a creative technique that involves repairing or replacing defective genes.

2. **Identify the Options**: The options provided are:
- Gene therapy
- Genetic recombination
- Gene cloning
- None of these

3. **Analyze Each Option**:
- **Gene Therapy**: This is a technique that uses nucleic acid polymers as a drug to treat diseases by correcting genetic abnormalities. It often involves replacing a mutated gene with a functional one.
- **Genetic Recombination**: This refers to the exchange of genetic material between different organisms, which results in offspring with combinations of traits. It does not specifically involve repairing or replacing defective genes.
- **Gene Cloning**: This is the process of locating and copying a specific gene of interest from an organism's DNA. While it involves genes, it does not focus on repairing or replacing defective genes.
- **None of These**: This option implies that none of the provided options are correct, which is not the case here.

4. **Determine the Correct Answer**: Based on the analysis, gene therapy is the only option that specifically involves the repair or replacement of defective genes.

5. **Conclusion**: The correct answer to the question is **Gene Therapy**.
