Genetically modified works by, firstly you have to identify a particular characteristic such as herbicide resistance. Then you get a gene which may come from a completely different organism, which is then inserted into some DNA from a plant cell, and that gives it trait. And that means for example if you spray some weed killer. The genetically modified crops would be unaffected. Plants can also be modified for pest resistance.

∙ 14y agoScientists (biotechnologists and biochemists) have altered the DNA structure (genetic material) of crops (genetic engineering) by identifying the desirable features from one particular species, and then cutting by a restriction enzyme, and then inserting desirable trait into the other species so the GM crops and foods can reproduce with the desirable features. These desirable features could be genes that code for resistance to disease, such as viruses, bacteria, and fungi (or mould) on the food or crop, or improving the taste of the food or crop by selecting the best gene for good taste, or even having a good effect on health, such as humans' immune system being boosted from a particular gene that fights diseases, and etc.

How do scientists genetically modify watermelons?
Most of the food plants we use now are 'genetically modified' in the way of improving the amount of food able to be grown, the disease resistances of the plant, the quality and consistency of the food grown - but then farmers have been doing this type of work for hundreds of years, the scientists have only recently taken up the habit
Are plant hormones used to genetically modify dwarf wheat plants?
i have no clue! i need to know as well!
Why do you need genetically modified food?
There is a lot of talk about how genetically modified food is needed, but no real evidence that it is needed.
What is genetically modify food used for?
Its normally used for pre made or pre mixed foods such as a tv dinner or ready made meals. Because it has been genetically modifyed it will last longer and wont go 'bad' for some time unlike organic foods. Furthermore, it can be used for animal foods and suppliments in many foods for animals as well.
How long have humans been trying to genetically modify animals?
In the sense that selective breeding can be considered genetic modification, humans have been genetically modifying animals since prehistoric times.
What can happen if you eat food that's not been genetically modified?
death. Nothing, food that hasn't been genetically modified is natural food. The kind of food people have been eating for thousands of years. Something is more likely to happen to you if you eat genetically modified food.
