The technique involving insertion of a desired gene into the DNA of plasmid vector is know as

Options

A. Gene splicing
B. Gene dressing
C. Gene cloning
D. Gene drafting

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about a specific technique that involves the insertion of a desired gene into the DNA of a plasmid vector.

2. **Identifying Key Terms:**
- **Desired Gene:** This is the gene that researchers want to insert into another organism.
- **Plasmid Vector:** A plasmid is a small circular piece of DNA that is separate from chromosomal DNA and can replicate independently. It is often used in genetic engineering to transfer genetic material.

3. **Analyzing the Options:**
The options provided are:
- Gene Splicing
- Gene Dressing
- Gene Cloning
- Gene Drafting

4. **Defining Each Option:**
- **Gene Splicing:** This refers to the process of modifying a gene after transcription, allowing a single gene to code for multiple proteins.
- **Gene Dressing:** This term is not commonly used in biotechnology.
- **Gene Cloning:** This is the process of creating copies of a specific gene or DNA segment by inserting it into a plasmid vector, which can then replicate within a host cell.
- **Gene Drafting:** This involves changes in allele frequency due to proximity to another gene under selection, not directly related to gene insertion.

5. **Selecting the Correct Answer:**
Based on the definitions and the context of the question, the correct answer is **Gene Cloning**. This technique specifically involves the insertion of a desired gene into a plasmid vector for replication and study.

6. **Conclusion:**
Therefore, the technique involving the insertion of a desired gene into the DNA of a plasmid vector is known as **Gene Cloning**.
