Match Column-I with Column-II and choose the correct option of the following:
| Column–I | Column– | ||
| Transgenic tobacco | Vitamin A | ||
| Golden rice | Alpha-lactalbumin | ||
| Transgenic Rosie cow | Pest resistant variety | ||
| Transgenic animals | Alpha-1-antitrypsin |
Options:
Answer:
Solution:
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 (alpha-1 antitrypsin) used to treat emphysema. Similar attempts are being made for the treatment of phenylketonuria (PKU) and cystic fibrosis. In 1997, the first transgenic cow, Rosie, produced human protein-enriched milk (2.4 grams per litre). The milk contained the human alpha-lactalbumin and was nutritionally a more balanced product for human babies than natural cow-milk.
Several nematode parasitises are harmful to a wide variety of plants and animals, including human beings. A nematode Meloidogyne incognita infects the roots of tobacco plants and causes a great reduction in yield. A novel strategy was adopted to prevent this infestation, which was based on the process of RNA interference (RNAi). The transgenic plant, therefore, got itself protected from the parasite.
Golden rice is biofortified rice with rich vitamin A content.
