Match List-I with List-II.
| List-I | List-II |
| A. Rosie | 1. Cry protein |
| B. α-1-antitrypsin | 2. Patent terms and emergency provisions |
| C. Second amendment of the Indian Patents Bill | 3. Emphysema |
| D. Bt cotton | 4. Transgenic cow |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-4, B-3, C-2, D-1
(A) Rosie — this matches (4) Transgenic cow. In 1997 Rosie, the first transgenic cow, gave milk enriched with a human protein (human alpha-lactalbumin). This milk was nutritionally more balanced for human babies than natural cow-milk.
(B) α-1-antitrypsin — this matches (3) Emphysema. It is a human protein made by transgenic animals and is used to treat emphysema.
(C) Second amendment of the Indian Patents Bill — this matches (2) Patent terms and emergency provisions. The amendment was made to deal with unauthorised use of our bio-resources, and it covers patent terms, emergency provisions, and research and development initiatives.
(D) Bt cotton — this matches (1) Cry protein. Bt cotton carries cry genes from Bacillus thuringiensis. The proteins coded by cryIAc and cryIIAb kill the cotton bollworms.
NCERT Extract:
Transgenic Animals – “… 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. Similar attempts are being made for treatment of phenylketonuria (PKU) and cystic fibrosis. In 1997, the first transgenic cow, Rosie, produced human protein-enriched milk (2.4 grams per litre).”
Ethical Issues – “… The Indian Parliament has recently cleared the second amendment of the Indian Patents Bill, that takes such issues into consideration, including patent terms of emergency provisions, research, and development initiatives.”
Biotechnological Applications in Agriculture – “… The toxin is coded by a gene cryIAc named cry. There are a number of them, for example, the proteins encoded by the genes cryIAc and cryIIAb control the cotton bollworms, that of cryIAb controls corn borer.”
