About GM food..........?

Question

So the DNA of the particular nutrient is encased in a bacterium's cell? (or is that the virus's cell?)

Anyway, are the DNA of the bacterium taken away from it entirely? What about the nucleus of the bacterium/virus? Wouldnt it command its DNA to replicate while the nutrient encased is still there?

And if that is already in our food, how much is the chance that we'll die of the virus/bacterium?

Answer 1

That's not how GMO works.

We use bacteria as a "vessel" to expand the number of copies of the gene-of-interest (the gene might give resistance to a herbicide or a disease, it might increase the size or longevity of the crop, it might give extra nutrition, or any number of other things).

So we insert the gene into a plasmid - a short loop of DNA found in bacteria that is NOT part of the normal bacterial chromosome (and bacteria don't have a nucleus, BTW). As the bacteria grow and multiple, each new bacterium will synthesise and contain copies of this plasmid - so we get more of the plasmid, and more of the gene.

After we have enough genes, we kill the bacteria and extract all the DNA. We purify it so we *only* have the plasmid with our gene-of-interest. We remove that gene from the plasmid, and we insert it into plant cells (there are a number of ways of doing this).

These plant cells now contain that gene - and no bacteria. We can then grow entire plants from those cells. The seeds those plants produce will also contain the gene - and we can use those seeds to grow more plants, which will also contain the gene.

Answer 2

I dont think your question is right. Genetically modified food like modern seedless fruits and many more high yielding crops have nothing to do with bacterial/viral genome. They are sometimes used as vectors to introduce new genes of desirable traits into pre-existing genetic makeup of that particular species. When they have introduced the desirable gene into one particular now modified cell we can propagate that one cell to full grown plant normally /animal (not common). So you are very safe eating GM food. Scietifically They get digested without giving any diseases.
