Weeds that have developed resistance to herbicides such as glyphosate may require higher amounts of glyphosate and perhaps other herbicides to keep them in check, and this means that herbicide-tolerant crops will be exposed to higher levels of herbicides as well. Insect-resistant crops contain genes from the soil bacterium Bacillus thuringiensis (Bt). GMFs, or Genetically Modified Foods(Also called GMOs), are foods that have had their DNA altered to benefit the food's nutrient value, pesticide and disease resistance, and even their shape and smell. Transgenic plants are the plants which have been genetically modified utilizing recombinant DNA technology to express exogenous genes or modify endogenous genes (Key et al., 2008)..
