MCQ
Why are transgenic animals used to test vaccine safety instead of directly on humans?
✅ Correct Answer: D
Transgenic mice help predict vaccine safety outcomes before proceeding to human trials.
Assertion-Reason
Assertion (A): Current treatments for ADA deficiency provide therapeutic benefits.
Reason (R): Both bone marrow transplantation and enzyme replacement therapy are not completely curative approaches.
✅ Correct Answer: B
Both statements are true from NCERT. NCERT states treatments exist: “In some children ADA deficiency can be cured by bone marrow transplantation; in others it can be treated by enzyme replacement therapy” and “The problem with both of these approaches that they are not completely curative.” However, the Reason doesn’t explain WHY treatments provide benefits - it states their limitation. Both facts are true but unrelated explanatorily.
NEET 2025 Pattern
Which of the following statements correctly describe the roles of transgenic animals?
S1: They are designed to study how genes are regulated and affect normal body functions and development.
S2: They are used to produce biological products such as human α-1-antitrypsin for treating specific human diseases.
S3: Transgenic animals are primarily created to enhance the overall biomass and yield of agricultural livestock.
S4: Transgenic mice are utilized for testing the safety of vaccines before human application.
S5: They serve as models for human diseases like cancer, cystic fibrosis, and Alzheimer’s, aiding in new treatment investigations.
✅ Correct Answer: C
Transgenic animals are designed to study gene regulation and its effects on normal body functions and development (S1 is correct). They are used to produce biological products like human α-1-antitrypsin for therapeutic purposes (S2 is correct). Enhancing overall biomass and yield of agricultural livestock is not listed as a primary role of transgenic animals in the NCERT text (S3 is incorrect). Transgenic mice are indeed used for vaccine safety testing (S4 is correct). They serve as models for various human diseases, including cancer, cystic fibrosis, and Alzheimer’s, to investigate new treatments (S5 is correct). Therefore, statements S1, S2, S4, and S5 are correct.
Tested Concept: Multiple roles and applications of transgenic animals.
