17. Basmati rice is distinct for its length of grain alone and 270 documented varieties of Basmati are grown in India.

18. rDNA technology involves the use of restriction endonucleases, DNA ligase, appropriate plasmid or viral vectors to isolate and ferry the foreign DNA into host organisms, expression of the foreign gene, purification of the gene product, i.e., the functional protein and finally making a suitable formulation for marketing.

27. RNAi involves silencing of a specific mRNA due to a complementary dsRNA molecule that binds to and prevents translation of the mRNA (silencing).

28. Insulin used for diabetes was earlier extracted from pancreas of slaughtered cattle.

29. Several nematodes parasitise a wide variety of plants and animals including human beings.

30. In India, 12 recombinant therapeutics are presently being marketed.
