Question
Some plants are made resistant to pests by using a gene from
- Bacteria
- Corn
- Pine trees
- Rice
Hint:
Some plants are made resistant to pests by using genes from bacteria.
The correct answer is: Bacteria
- Genetically modified crops that are resistant to pests, especially genetically modified cotton and maize, are hazardous to some insects.
- Because the introduced genes were first discovered in a bacterium species called Bacillus thuringiensis, they are frequently referred to as Bt crops.
- Cry toxins are a class of poisons that these bacteria create.
