14. A bio reactor provides optimum pH to cultivate fungal cell for achieving the desired recombinant products.

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

16. Indian Government has set up organisations such as GEAC (Genetic Engineering Approval Committee), which will make decisions regarding the validity of GM research and the safety of introducing GM-organisms for public services.

17. rDNA technology involves the use of making a suitable formulation for marketing.

18. Biotechnology essentially deals with industrial-scale production of biopharmaceuticals using genetically modified fungi.

19. Insulin from a cattle or pig, results in all patients to develop allergy or other types of reactions to the insulin protein.

20. The first restriction exonuclease–Hind II, whose functioning depended on a specific DNA nucleotide sequence, was isolated and characterised in 1970s.

21. Biotechnology deals with small scale production and marketing of products and processes using live organisms, cells or enzymes.

22. Transgenic cow-milk is nutritionally a more balanced product for human babies than natural cow-milk.

23. GM plants have been useful to increase post-harvest losses.

24. The normal E. coli cells do not carry resistance against chloramphenicol.

25. Rene Descartes is the French biologist.

26. The hormones are not species-specific.

27. If we are not vigilant, and we do not immediately counter patent applications like Basmati, other countries/individuals may encash on our rich legacy, and we may not be able to do anything about it.

28. Biotechnology, the twentieth century off-shoot of modern biology, changed our daily life as its products brought qualitative improvement in health and food production.

29. The manipulation of living organisms by the human race cannot go on any further, with regulation.

30. The recombinant DNA technology has made immense impact in the area of healthcare.

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

32. RNAi involves silencing of all mRNA due to a complementary dsDNA molecule that binds to and prevents transcription of the mRNA (silencing).

33. Hind II recognises a specific palindrome sequence and always cuts DNA molecules at random points.

49. The diversity of rice in India is one of the richest in the world.

50. Stanley Cohen observed that restriction enzymes have the capability of cutting DNA strands in a particular fashion, which left what has become known as ‘sticky ends’ on the strands.
