What is recombinant DNA technology?

• A. A method used to isolate specific genes
• B. A process of combining DNA from different sources to create new genetic combinations
• C. A technique for producing RNA molecules
• D. A form of gene therapy

Answer: (B)

Recombinant DNA technology is defined as the process of combining DNA from different sources to create new genetic combinations. This technique involves the manipulation of genetic material to produce sequences that do not occur naturally. By using enzymes, scientists can cut and splice DNA segments from various organisms, leading to the creation of recombinant molecules. This is crucial for various applications in biotechnology, including the production of insulin, the development of genetically modified organisms (GMOs), and advancing gene therapy techniques.

The significance of this technology lies in its ability to transfer desirable traits from one organism to another, facilitating advancements in medicine, agriculture, and research. The underlying principle of recombinant DNA technology is to utilize the genetic code of one organism and insert it into another, enabling the host organism to express new traits or produce specific proteins.
