Note: A similar question was also asked in CUET (UG) 2026 on 21-05-2026 (Slot 1) and on 18-05-2026 (Slot 1), and in CUET (UG) 2025 on 03-06-2025 (Slot 2).

NCERT Extract:
Transgenic Animals – “… Biological products: Medicines required to treat certain human diseases can contain biological products, but such products are often expensive to make. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema.”
