How is it done?
There are five major steps involved in creating genectically modified foods. The steps incude: DNA isolation, genecloning, gene designing, cell transformation, and backcross breeding. Here is the overview of this proccess:
-
Isolate DNA- DNA is extracted from another organism that has the desired trait.
- Clone Genes- After the desired trait is located in the DNA it is then copied.
- Design Genes- The gene of the desired trait is inserted into a plant cell which then is included into a chromosome of the plant cell. The trait that it codes for will be included in the cell's offspring.
- Cell Tansforms- The cell then reproduce and grow new plants that contains the trangene in all of its cells.
- Breeding Plants- Seeds obtained from improved plants are then given to farmers to produce more crops with fewer defects.
Through this process, genetically modified foods are created to increase production with more advantages. This method results in foods that can be sold in markets all over the world.
 | What allow crops to be modified? Agrobacterium tumefaciens is a plant pathogen that allows scientists the ability to transfer genes from one organism to another. They change the production in the plant hormones by transferring their own DNA into the plant. This infection is harmful to plants, yet very useful to scientists. Besides allowing scientists to transfer genes, it is known as the standard tool for investigating plant genetics and modifying crops. |
Why are they produced? GM foods are produced because there are many advantages for producers and consumers. Producers are able to manufacture foods at a faster rate with fewer defects. Producers benefit because the foods would be developed at a lower price. Meanwhile, consumers are able to enjoy GM foods that now contain more nutritional value than they have been before. The reason behind creating genetically modified foods was to improve the protection of crops and increase the rate of production. In order to increase the protection of the crops from viruses or diseases caused by insects, genetic technology allowed the crops to have increased tolerance towards herbicides. This technique would kill insects who cause harm to the crops and also, do no harm to people who consume them. |  |
