Study Notes

What are Genetically Modified Foods?

Genetically modified foods, also called genetically modified organisms (GMOs), involve the insertion of DNA from one organism into another or modification of an organism's DNA to achieve a desired trait.

Examples of GMOs

Golden rice: contains beta-carotene (Vitamin A), not found in regular rice.
Bt corn: contains a chemical normally found in a bacterium (Bacillus thuringiensis) that is toxic to insects but not to humans.
Herbicide-resistant plants.

How are Genes Modified?

Restriction enzymes are used to "cut" DNA segments from one genome.
DNA ligases are used to "paste" them into another genome.

How are Animals and Plants Targeted?

Microinjection method: injects a solution of DNA into a developing embryo.
Agrobacterium: used to infect plants with a gene of interest.
Particle gun: shoots small bits of metal coated with the gene into the plant.

How Common are GM Foods?

48 foods have been approved for use by the Canadian Food Inspection Agency.
Examples: corn, canola, potatoes, tomatoes, squash, soybeans, and more.
Labeling of GM foods is not mandatory unless there is a health or safety concern.

Potential Benefits

Pest resistance
Herbicide resistance
Cold tolerance
Drought tolerance
Increased nutrition
Edible vaccines
Reduced use of herbicides and chemicals in farming.

Potential Environmental Hazards

Reduced effectiveness of pesticides as insects become resistant to engineered toxins.
Harm to other organisms (e.g., monarch butterfly larvae).
Gene transfer to non-target species.
Loss of biodiversity.

Potential Human Health Risks

Allergens
Unknown health risks due to interactions between biological processes.

Economic Hazards

Elimination of competition
Suicide seeds
Dependence on companies for seeds.
