What is GM Food?What is GM Food?GM food stands for Genetically Modified
FoodGM food is food with genes modified.
Genes can be transplanted by taking out useful pieces of DNA from one organism and merging them with the DNA in another organism.
Through this process the quality, the nutrient value, the yield or the resistance against pest of the plant will increase. Hence the food supply and the standard of life of human will be increased.
