To protect a farm animal from a plant toxin, a gene for resistance to the toxin was transferred to the farm animal.Which technique is used to obtain this objective?
Correct answer: D. Genetic engineering
- A. Cloning
- B. Tissue culture
- C. Gene therapy
- D. Genetic engineering
Explanation
The correct technique used to transfer a gene for resistance to a toxin into a farm animal is Genetic engineering. This process involves directly manipulating the DNA of an organism to introduce new traits, such as resistance to toxins. In contrast, Cloning is about creating identical copies, Tissue culture is about growing cells in vitro, and Gene Therapy is a medical treatment focused on correcting defective genes in humans rather than transferring genes to animals.
