For which of the following human disease, transgenic model was not developed?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → AIDS
Option (1) AIDS — No transgenic model has been developed. AIDS is not in NCERT’s list of human diseases with transgenic animal models.
Option (2) Cancer — A transgenic model has been developed. Transgenic animals that carry cancer-related genes are used to study how the disease develops and to test new treatments.
Option (3) Cystic Fibrosis — A transgenic model has been developed. Cystic fibrosis is a genetic disease, and transgenic animals serve as its model.
Option (4) Rheumatoid arthritis — A transgenic model has been developed. It too is among the diseases for which transgenic models exist.
Note: A similar question was also asked in CUET (UG) 2023 on 28-05-2023 (Slot 1).
NCERT Extract:
Transgenic Animals – “… (ii) Study of disease: Many transgenic animals are designed to increase our understanding of how genes contribute to the development of disease. These are specially made to serve as models for human diseases so that investigation of new treatments for diseases is made possible. Today transgenic models exist for many human diseases such as cancer, cystic fibrosis, rheumatoid arthritis and Alzheimer’s.”
