A technique of deliberate manipulation of genes/transfer of gene to a different organism is

Options

A. Genetic engineering
B. Gene therapy
C. Tissue culture
D. None

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a technique that involves the deliberate manipulation of genes or the transfer of genes to a different organism.

2. **Identifying Key Terms**: The key terms in the question are "deliberate manipulation of genes" and "transfer of gene to a different organism."

3. **Evaluating Options**: The options provided are:
- Genetic engineering
- Gene therapy
- Tissue culture
- None

4. **Analyzing Each Option**:
- **Genetic Engineering**: This is a technique that involves altering the genetic material of an organism. It includes the transfer of genes from one organism to another, which fits the description in the question.
- **Gene Therapy**: This involves inserting genes into a patient’s cells to treat or prevent disease, not necessarily transferring them to a different organism.
- **Tissue Culture**: This is a method of growing cells or tissues in a controlled environment, typically for research or medical purposes, but it does not involve gene transfer.
- **None**: This option implies that none of the provided techniques fit the description, which is incorrect since genetic engineering does.

5. **Conclusion**: Based on the analysis, the correct answer is **Genetic Engineering**. This technique allows for the manipulation and transfer of genes between organisms.

**Final Answer**: The technique of deliberate manipulation of genes/transfer of gene to a different organism is **Genetic Engineering**.
