AExpert Answer

The study referred to looked at the question of whether fragments of DNA, consumed in our food, could pass into the blood stream. The main finding was that this could happen and that fragments of DNA large enough to contain whole genes could enter the human circulation system. Previous to this study, it was thought than DNA would be completely degraded during the digestion process. We consume large amounts DNA from plants in our everyday diet. If the diet contained some GM products then some of the DNA consumed could come from this source. DNA from a GM plant source would be no different to DNA from any other source. If DNA from our food can pass into the blood stream then this has always happened and has caused us no problems. The study does not in any way claim that GM foods can alter human DNA and there is no evidence at all for this.

The UPC (Universal Product Code) is a barcode (which has numbers beneath it) which identifies the product and the manufacturer. I think you may be thinking of the PLU (Price Look Up) code which is the 4 or 5 digit number on produce used to link a price with an item. The PLU code is a voluntary program that assigns numbers to produce items, this helps cashiers identify the correct price for a produce item. Growers/Packers can use the number "9" prefix to this 4-digit numeric code to... Read More

Thank you for your question. There are various aspects of your question. I assume your question refers to the use of Agrobacterium rhizogenes by scientists to intentionally transfer genes from the bacterium to plants. Infection and DNA transfer from this bacterium occurs in nature all the time to cause disease. Such transformed plants are not classified as GMOs since transfer occurred naturally. If this is done by scientists then it would be classified as a GMO. Rules and...

I’m a Monsanto scientist who has more than 20 years of experience with genetic modification of plants. I will try to answer your question, even though I don’t ever do experiments on animals, certainly not on humans, of course! Can humans be genetically modified…but a much bigger question is should humans be genetically modified? There are two ways to think about genetic modification of humans (or any animal). One way is modification of somatic cells, and the other is the... Read More
