The DNA molecule to which the gene of interset is integrated for cloning is called

Options

A. Carrier
B. Transformer
C. Vector
D. Template

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the DNA molecule that is used to integrate a gene of interest for cloning purposes.

2. **Identifying the Key Concept**: In biotechnology, when we want to clone a gene, we need a specific type of DNA molecule that can carry this gene into a host organism. This is crucial for the process of creating recombinant DNA.

3. **Defining the Term**: The DNA molecule that carries the gene of interest is referred to as a "vector." Vectors are essential tools in genetic engineering because they facilitate the transfer of genetic material.

4. **Role of the Vector**: The vector acts as a vehicle that not only carries the gene of interest but also allows it to replicate within the host organism. This is important for producing multiple copies of the gene or the protein it encodes.

5. **Examples of Vectors**: One of the most well-known vectors is the plasmid called PBR 322. This plasmid contains elements necessary for replication and the ability to insert foreign DNA, making it a suitable choice for cloning.

6. **Conclusion**: Therefore, the DNA molecule to which the gene of interest is integrated for cloning is called a "vector."

**Final Answer**: Vector
