Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes genetic modification?
A
It allows large quantities of medications to be produced.
B
It is used to alter crops to become insect-resistant.
C
It improves the removal of pollution from soil and water
D
None of these options describe genetic modification
Explanation: 

Detailed explanation-1: -Bacillus thuringiensis (Bt) crops are plants genetically engineered (modified) to contain the endospore (or crystal) toxins of the bacterium, Bt to be resistant to certain insect pests.

Detailed explanation-2: -Definition. 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.

Detailed explanation-3: -Genetic modification of plants involves adding a specific stretch of DNA into the plant’s genome, giving it new or different characteristics. This could include changing the way the plant grows, or making it resistant to a particular disease.

Detailed explanation-4: -Bacillus thuringiensis (Bt) corn is a GMO corn that produces proteins that are toxic to certain insect pests but not to humans, pets, livestock, or other animals. These are the same types of proteins that organic farmers use to control insect pests, and they do not harm beneficial insects, such as ladybugs.
