1. What is a transgenic food?

A genetically modified organism is characterized by contain a fraction of the DNA from another agency integrated into their own DNA. In other words, the GMO presents a new piece of DNA that distinguishes it from its conventional counterpart.

2. Historical Background

Towards 11000 a.C. men primitive "tamed" the first plant variety for food.

In 6000 a.C. manufacturing the beer in Mesopotamia

15TH century the first peppers similar size pepper

grain achievement of successive selections of the best seed be increased the size.

19TH century Pasteur enunciates the theory of biological fermentation

Mendel makes all tests on the transmission of characters in the

peas

3. What is genetic information?

ORGANISM DNA GENE

their characteristics are is stored in the Strech of DNA that determined by genetics nucleus of her cells determined the chara- cteristics of the body

4.How is made ?

DNA extracted from an organism

Another body, is extracted protein gene we want to implement

the transgene with the genetic information if implanted in organism that we can change his characteristics.

Genetically engineered cloned, modified, and gene fragments

DNA is introduced to the tomato without damaging the cell.

5. FIRST MARKETING

May 18, 1994 when the Food and Drugs (DEA) of E. E. U. U. authorize the marketing of the first food with a gene

"strange“. Flavr Svr . This tomato had beenmodified to resist any longer after ripening.

6. How are GM foods?

Nowadays we currently serve only a few genetically modified vegetables

Another major product is the GM soy. In this case, what has beendone is to introduce a gene that makes it resistant to a herbicide.

How are GM foods?

Transgenic maize has been obtained to be resistant to an insect,the corn borer and herbicide.

The prospects of this technology are vast. and there are severaldozen more plants close to the market, and in the coming years thenumber will rise to hundreds.

7. Goals

It`s herbicide-tolerant

Transgenic Food disease-resistant caused by a virus, bacteria and fungi.

Transgenic Food cold-resistant.

You can get varieties of transgenic plants in need minus water.

. This could help combat undernourishment in developing countries of the third world.

8. Public risks of transgenic food Emergence of antibiotic resistance in bacteria

pathogenic to humans.

Genetic contamination isirreversible and unpredictable.

endangered species and varieties traditionally grown.

Emergence of new allergies by introducing new proteins in food.

Increased food contamination by greater use of chemicals in agriculture.

9. Ignorance

The spanish people is fed a lot of transgenics without know it.

Nor do we know if a lot of mealt, milk or eggs from animals fed transgenic feed,  only label and is not required to label the finished products.

Corn, soybeans or their industrial derivatives are

present in more than 60 percent of processed foods, from chocolate to potato chips, to margarine and foods.
