Statement A : Genetically modified crops are less expensive than agrochemicals Statement B : Gene Revolution succeeded in tripping the food supply
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
GM seed is expensive, so farmers planting these varieties earn less profit. In marginal land, however, reduced pest damage can mean the difference between profit and loss, so GM crops can enable profitable farming in areas where it might not otherwise be possible. The Green Revolution succeeded in tripling the food supply but yet it was not enough to feed the growing human population. Increased yield have mainly been due to the use of better management practices and agrochemicals (fertilisers and pesticides) but partly been due to the use of improved crop varieties. Both statements are incorrect.

Bacillus thuringiensis forms protein crystals which contain insecticidal protein
1 Is activated by acid \(\mathrm{pH}\) of the foregut of the insect pest
2 Is coded by several genes including the gene cry
3 Binds with epithelial cells of midgut of the insect pest ultimately killing it
4 Does not kill the carrier bacterium which is itself resistant to this toxin
Explanation:
Bacillus thuringiensis forms protein crystals which contain insecticidal protein because they have the ability to bind with the midgut epithelium of the insect pest and create pores killing it.

Cry gene containing crops needs
1 No insecticide
2 Little amount of insecticide
3 Large amount of insecticide
4 None of the above
Explanation:
cry gene containing crops need no insecticide because cry gene produces protein which makes the plant pest resistance.

Which of the following are the critical research areas of biotechnology?
1 Providing best catalyst
2 Creating optimal conditions for catalyst function
3 Downstreaming processing technique
4 All of the above
Explanation:
Three critical research areas of biotechnology are: (i) Providing the best catalyst in the form of improved organism usually a microbe or pure enzyme. (ii) Creating optimal conditions through engineering for a catalyst to act, and (iii) Downstream processing technologies to purify theprotein/organic compound.
