BIOXII12: BIOTECHNOLOGY AND ITS APPLICATIONS
347679
Statement A : A crop expressing cry gene is usually resistant to specific insects Statement B : cry' proteins produced from Bacillus thuringiensis is toxic to certain insects
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:
Each Cry protein is toxic to a different group of insects. The gene encoding Cry protein, that is cry gene has been isolated and transferred into several crops. A crop expressing a cry gene is usually resistant to the groups of insects.

Statement A : Genetically engineered crop-based agriculture is used for increasing food production Statement B : Genomes of many plants are manipulated or altered by combining them with other genes to get deisred traits.
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:
Crops are genetically modified to allow higher yields due to the production of molecules that are toxic to insect pests, but have no effect on animals and humans. These crops are not devoured by insect pests, and lead to higher incomes for farmers due to better crop yield and lowered use of chemical pesticides. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA. Both statements are correct.

Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called
1 Recombinant organisms
2 Hybrid organism
3 Genetically modified organisms
4 Super-organisms
Explanation:
Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO).

Insect resistant transgenic cotton has been produced by inserting a piece of DNA from
1 Insecta
2 Prokaryote
3 Protista
4 A virus
Explanation:
Insect resistant transgenic cotton has been produced by inserting a piece of DNA from a bacterium -prokaryote Bacillus thuringiensis into the genome of cotton.
