Question

Transgenic animals are produced by man. Explain any three ways in which such animals can be beneficial to humans.

Hint:

Remember: Transgenic animals can contribute significantly to medical advancements, agriculture, and industrial applications by providing resources that are otherwise difficult or impossible to produce.

Answer 1

Step 1: Introduction to transgenic animals.
Transgenic animals are genetically modified organisms that contain genes from other species. These animals are created using biotechnology techniques such as gene transfer or gene editing.
Step 2: Three benefits of transgenic animals to humans.
1. Medical Research: Transgenic animals can be used in medical research to study human diseases, develop treatments, and test drugs. For example, genetically modified mice are used to study cancer, Alzheimer's, and other conditions.
2. Organ Transplants: Animals like pigs can be genetically modified to grow organs that are compatible with human transplants. This could help address the shortage of organs available for donation.
3. Enhanced Production: Transgenic animals can be engineered to produce valuable proteins, such as human insulin or clotting factors, which can be harvested for medical use.
Step 3: Conclusion.
Transgenic animals have the potential to revolutionize medicine, agriculture, and biotechnology, benefiting humans in various ways.
