Making a genetically identical copy of DNA or of an organism?

• A. Gene Therapy
• B. Tuberculosis
• C. Active Listening
• D. Cloning

Answer: (D)

Cloning is the process of creating a genetically identical copy of DNA or an organism. In DNA cloning, a specific DNA fragment is duplicated to produce many identical copies, which helps scientists study genes or produce proteins. In organism cloning, an entire organism is generated that is genetically identical to the donor, as with Dolly the sheep. The other terms describe different ideas: gene therapy aims to treat diseases by delivering or editing genes rather than copying genetic material; tuberculosis is a contagious disease caused by a bacterium; active listening is a communication skill focused on understanding another person. So cloning best fits the idea of making an identical copy.
