Question

Genetic engineering has been successfully used for producing

• A. Animals with inferior traits.
• B. Transgenic mice for testing safety of polio vaccine before use in humans
• C. Animals that have the same genetic constitution.
• D. None of the above

Answer 1

Answer: (B)

Transgenic mice for testing safety of polio vaccine before use in humans

Transgenic mice are being formed for use in testing the safety of vaccines before they are used on human beings. Transgenic mice are being used to test the safety of the polio vaccine. Many transgenic animals are developed to increase our understanding of how genes contribute to the development of disease so that investigation of new treatments for diseases is made possible. Now transgenic models exist for many human diseases such as cancer, cystic fibrosis, rheumatoid arthritis, Alzheimer's disease, haemophilia, thalassemia, etc.

Therefore, the correct answer is option B.
