Recombinant DNA Therapeutics — NEET Biology

📚 Practice Concept
📖 NCERT Source

The recombinant DNA technological processes have made immense impact in the area of healthcare by enabling mass production of safe and more effective therapeutic drugs. Further, the recombinant therapeutics do not induce unwanted immunological responses as is common in case of similar products isolated from non-human sources. At present, about 30 recombinant therapeutics have been approved for human-use the world over. In India, 12 of these are presently being marketed.

Correct answer: C If assertion is true but reason is false.

NCERT confirms recombinant therapeutics are preferred for medical use. However, NCERT states “The recombinant therapeutics do not induce unwanted immunological responses as is common in case of similar products isolated from non-human sources” - it’s non-human products that cause immune responses, not recombinant therapeutics. The Reason reverses this key advantage.
