GENETICALLY MODIFIED FOODBY: Kelsey Lykins

• Is an organism whose genetic material has been altered using genetic engineering techniques

What is a GMO?

Some Examples:

Tomatoes

Carrots

Peas

TECHNIQUES1.) Bacterial Carriers- Bacterium in a solution is used to make the cell wall

porous. Then the selected gene is inserted into the plasmid. After heated, the plasmid and bacterium show the new gene.

2.) Calcium Phosphate Precipitation- The chosen DNA is exposed to calcium phosphate which then creates granules. These are ingested and release DNA into the host’s nuclei.

3.) Biolistics- The chosen DNA attaches to gold particles and are forced into the target’s cell by using a short burst of gas.

Why are foods Genetically Engineered?

They have a higher nutritional value and taste better. Crops can grow in poor soil or

in adverse climates.

Some are pest resistant and have longer growing seasons. Resistant to weeds and

disease.

They also stay ripe longer.

Disadvantages

GMO’s don’t have to be labeled.

Pests would adapt to the pesticides and be harder to get rid of.

Would bring an end to food diversity.

Could possibly cause allergies in humans.

More Modified Food!

Potatoes have a longer growing season and are pest resistant.

Sugar cane is pest resistant.

Soy beans are resistant to herbicides.

AND MORE FOOD…

Canola is virus resistant.

Rice is modified to contain more vitamin A.
