What is gene cloning?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Gene Cloning**: Gene cloning is the process of creating multiple identical copies of a specific gene. This is essential for various applications in biotechnology, particularly in recombinant DNA technology.

2. **Purpose of Gene Cloning**: The multiple copies of the gene are used in research, medicine, and agriculture. They allow scientists to study gene function, produce proteins, or develop genetically modified organisms.

3. **Polymerase Chain Reaction (PCR)**: The primary method used for gene cloning is the Polymerase Chain Reaction (PCR). This technique amplifies the gene of interest, producing millions or even billions of copies.
