9. 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.

11. Management of adult-onset diabetes is possible by taking insulin at random intervals.

12. There is growing public anger that certain companies are being granted patents for products and technologies that make use of the genetic materials, plants and other biological resources that have long been identified, developed, and used by farmers and indigenous people of a specific region/country.

13. Biotechnology essentially deals with industrial-scale production of biopharmaceuticals using genetically modified eukaryotes.

14. From bioreactor small volumes of the culture can be withdrawn.

15. Hind II recognises a specific palindrome sequence but mostly cuts DNA molecules at random points.

16. Basmati rice is distinct for its unique aroma and flavour and 27 documented varieties of Basmati are grown in India.

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

18. Bioreactors can be thought of as vessels in which raw materials are chemically converted into specific products, individual enzymes, etc., using plant, animal, microbial or human cell.

19. Rice is an important food grain, the presence of which goes back thousands of years in Asia’s agricultural history.

20. RNAi takes place in all prokaryotic organisms as a method of cellular defence.

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

22. Ever since the days of Rene Descartes, the French philosopher, mathematician and biologist of seventeenth century, all human knowledge especially natural sciences were directed to develop technologies which add to the creature comforts of human lives, as also value to human life.

23. Descartes’ approach to understanding natural phenomena introduced a distinctly anthropocentric perspective.

24. Patent rights on Basmati rice allowed the company to sell this ‘new’ variety of Basmati, in the US and abroad.

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

26. Hind II always cut DNA molecules at a particular point by recognising a specific sequence of seven base pairs.

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

28. Biotechnology essentially deals with industrial-scale production of biopharmaceuticals using genetically modified microbes, fungi, plants, and animals.

29. The rDNA technology enabled mass production of safe and more effective therapeutic drugs.

30. Several attempts have also been made to patent uses, products and processes based on Indian traditional herbal medicines, e.g., turmeric.

31. Hind II always cut DNA molecules at a particular point by not recognising a specific sequence of seven base airs.

32. Downstream processing technologies to purify the protein/organic compound is a critical research area of biotechnology.

33. Since the time of René Descartes, the 17th-century French philosopher, mathematician, and biologist, human knowledge, especially in the natural sciences, focused on developing technologies that did nothing to improve human comfort or add value to human life. Descartes’ approach to understanding natural phenomena rejected any anthropocentric view. Physics and chemistry remained separate from engineering and industry, with no intention of contributing to human welfare.

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

35. Insulin consists of two short polypeptide chains: chain A and chain B, which are linked together by disulphide bridges.

36. Physics and chemistry gave rise to engineering, technologies and industries which all worked for human comfort and welfare.

37. There are an estimated 200 varieties of rice in India alone.

38. The normal E. coli cells do not carry resistance against ampicillin.

39. DNAi takes place in all viruses as a method of cellular defence.

40. Hind II does not recognise a specific palindrome sequence yet mostly cuts DNA molecules at a particular point.

41. A bio reactor provides optimum temperature to cultivate bacterial cell for achieving the desired recombinant products.

42. A bio reactor provides optimum substrate concentration to cultivate bacterial cell for achieving the desired recombinant products.

43. Kanamycin sensitive gene in a plasmid could be considered as useful selectable markers for E. coli.

44. In 1967, the first transgenic animal, Rosie, produced human alpha-lactalbumin enriched milk.

45. A bio reactor provides required amount of oxygen to cultivate plant cell for achieving the desired recombinant products.

46. The patent extends to functional equivalents, implying that other people selling Basmati rice could be restricted by the patent.

47. Chloramphenicol sensitive gene in a plasmid could be considered as useful selectable markers for E. coli.

48. By not recognising a specific palindrome sequence, Hind II always cuts DNA molecules at a particular point.

49. Stanley Cohen was born in 1936.

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