Questions and Answers
Banana: A gene from a bacterium called Bacillus thuringiensis (Bt) that produces a toxin that kills insects1. This gene makes the banana resistant to the banana borer, a pest that damages the fruit. Corn: Several genes from different sources, such as Bt, a virus, and a petunia, that confer resistance to insects, herbicides, and drought.These genes make the corn more tolerant to environmental stresses and reduce the need for chemical inputs2. Cotton: A gene from Bt that makes the cotton resistant to the bollworm, a major pest that feeds on the cotton bolls. This gene reduces the amount of insecticide needed to protect the crop. Rice: A gene from a daffodil that produces beta-carotene, a precursor of vitamin A1. This gene makes the rice enriched with vitamin A, which can help prevent blindness and other health problems in people who lack this nutrient. Soybean: A gene from a soil bacterium that makes the soybean resistant to a herbicide called glyphosate. This gene allows the farmers to spray the herbicide on the field and kill the weeds without harming the soybean crop. Papaya: A gene from the papaya ringspot virus that makes the papaya resistant to the same virus2. This gene protects the papaya from a disease that can wipe out the entire plantation. Apple: A gene from an apple that suppresses the production of polyphenol oxidase, an enzyme that causes browning when the apple is cut or bruised1. This gene makes the apple stay fresh longer and reduce food waste.

Study Notes
Genetically Modified Organisms (GMOs)
Banana
- Resistant to banana borer, a pest that damages fruit, due to a gene from Bacillus thuringiensis (Bt) that produces a toxin that kills insects.
Corn
- Contains multiple genes from various sources (Bt, virus, petunia) that confer resistance to insects, herbicides, and drought.
- Makes corn more tolerant to environmental stresses and reduces the need for chemical inputs.
Cotton
- Resistant to bollworm, a major pest that feeds on cotton bolls, due to a gene from Bt.
- Reduces the amount of insecticide needed to protect the crop.
Rice
- Enriched with vitamin A due to a gene from a daffodil that produces beta-carotene, a precursor of vitamin A.
- Can help prevent blindness and other health problems in people who lack this nutrient.
Soybean
- Resistant to herbicide called glyphosate due to a gene from a soil bacterium.
- Allows farmers to spray herbicide on the field and kill weeds without harming the soybean crop.
Papaya
- Resistant to papaya ringspot virus due to a gene from the virus.
- Protects the papaya from a disease that can wipe out the entire plantation.
Apple
- Stays fresh longer and reduces food waste due to a gene that suppresses the production of polyphenol oxidase, an enzyme that causes browning when the apple is cut or bruised.
