Genetic Mutatuions in Crops
Pros of Genetically Modifying Crops
- Prevents various diseases
- Adds more nutrition to the crop
- Can survive more harsh environments
- Improved taste
- Faster Growth
- Pest resistance
Cons of Genetically Modifying Crops
- Costs more
- Massive amounts of funding
- Creation of super weeds
- Farmers in third world countries may not be able to afford genetically modified seeds.
- Unknown effects on human health
Genetically Modified Foods
Watermelon without seeds.
Doctors inject a vaccine into a potatoe. The potatoe prompted the immune system to create antibodies to fight off the disease.
Many people in poor countries suffer from extreme cases of vitamin A deficiency. Golden rice was genetically modified to contain more vitamin A to fight this deficiency.
Techniques of Agricultural Biotechnology
- One way to transfer a desired gene is to inject the DNA into a plant cell. Then, create an entirely new plant from tissue.
- Another way is to use a soil bacterium to transfer DNA into the plants.
- The last way is to use a gene gun to shoot through the cell wall and combine the DNA with the plants DNA.
The Gene Gun
- Genetically modified foods are allowed to be sold in the U.S. right now.
- Most of the states are now deciding whether or not to pass a bill that would force products that are genetically modified to be labeled as such.
- Maine and Connecticut have been the only 2 states to pass the law requiring GMOs to be labeled, but their acts go into place when other countries join them.
- This issue is costly for states to debate, and there is no clear winning side yet.
- Some companies have taken the issue into their own hands and pledged not to use GMOs
