Transcript of Genetic Modification

What is Genetically Modified Food?!?! Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have very small changes that are brought into the cell by genetic engineering techniques
Is it Safe?!? Experts say 60% to 70% of processed foods on U.S. grocery shelves have genetically modified ingredients The End!!! Did you know weve been eating GM foods like tomatoes since 1990's? I think we all should eat organi Farmers tomatoes would freeze up at night so scientists noticed that the artic flounder could withstand cold tempretures.Then they took the flounder DNA and put it inside the tomatoe DNA so the tomatoe wouldn't freeze. Now isn't that scary?! Think twice when buying produce. Well how do you modifie the cell? You have to invade the cell to deposit the desired gene. Well what do you need? Bacteria and viruses. First you have to cut out a sequence of DNA from the desired Gene, but if you insert it into the plant it will have no effect. So you get E.Coli and place the desired gene into it and they will connect to each other. Now you can smuggle the DNA into the plant they want to modify. .................... Long story short
you have to have
a virus or bacteria
to invade the cell.
Then you take the
desired gene and place
it into the cell. To put
the gene you can use elect-
ricity to make holes on the gene. Or use a gene gun which
fires gold particles what are the negatives
of GM foods? In the Philipeans people
living near the GM corn
field developed skin, repitory,
and intestinal problems. Blood
tests were done on 39 of the
Philipene people and it was
revealed that there immune
system were effected by the BT
toxin Bacillus thuringiensis
that the corn had released!
