Question

Transgenic hirudin is obtained from
A. Ocimum sanctum
B. Brassica napus
C. Potato
D. Tomato

Answer 1

Hint: Transgenic is the process of introducing one or more DNA sequences from another species by artificially. Animals which are made by transgenic animals have a small amount of foreign DNA. After that it is injected into the fertilized egg or developing embryo. The first transgenic animal is fruit flies and mice. These types of plants are produced for the biological active peptides and proteins. It possesses pharmaceutical application in the plants which are grown in a transgenic manner.

Complete answer:
Option A: Tulsi is known to be Ocimum sanctum. It has a lot of medical ingredients in it. All parts of this plant are used to treat diseases like cold, and cough. The Leaves, seeds, stems and flowers of these plants are used as medicine. It is the flowering plant under the mint family. It is native to the Indian subcontinent.
Option A is incorrect.
Option B: Brassica napus is also called as rapeseed or oil seed rape. It is also the flowering plant that produces the bright yellow color flowers. It is cultivated mainly to produce the oil. It contains a large amount of Erucic acid. It is the hybrid species which is resulting from inter-specific breeding between the Brassica Rapa and Brassica oleracea. It is the self-compatible pollinating species. This will produce the protein called hirudin and it avoids the blood clotting.
Option B is the correct answer.
Option C: Potatoes are the root vegetable. It is native to America. It is classified under the solanaceae family. It is cross pollinated by insects like bumblebees. It is not breaded by other plants in the same species.
Option C is incorrect.
Option D: Tomatoes are botanically classified by berries. This species is largely produced from central America and western south America. Native tomatoes are not a transgenic plant. If the tomato is taken for a genetic experiment, then other genomes are inserted through it for increasing the lifetime of the tomatoes. But it is not producing the transgenic hirudin.
Option D is incorrect.

Therefore, Option B is the correct answer.

Note:
Hirudin is the anticoagulant protein produced by the plant oleosin is used as a carrier during the production of leech. Tomato is the first transgenic plant entered into the market. Beta glucuronidase is produced by the Brassica carinata Braun or Ethiopian mustard which uses the oleosin as the carrier and produces the hirudin. Transgenic potato plants are highly rich in protein. Nutrient quality is high in the transgender tomato. All transgenic plants are high in proteins and nutrients.
