Genetics google books

Genetically engineered food is food which is enhanced by the addition of genes from different species to make them better. Genes are, in the most basic interpretation, codes that are responsible for certain characteristics, the production of certain enzymes or to create a certain appearance, and in the case of genetically engineered food the genes are often put in place to create enhanced versions of regular food. Since it is quite a costly process to develop, genetically engineered food is patented by large corporations that are responsible for their research and development.In the face of medical research however the increased benefits of organic food over conventional food stuff is yet to be proven, which has led the even the FDA and the USDA to claim that non organic food is just as nutritious as organic food stuff. However certain foods do carry some superior benefits of organic food, for example it has been revealed that organic milk and tomatoes are far superior to it s non organic counterparts. For example organic milk is shown to contain more antioxidants and Omega 3 fatty acids and vitamins than non organic milk. These findings are according to the University of Aberdeen?s Danish Institute of Agricultural Research and the Institute of Grassland and Environmental Research, who claim that organic milk is of better nutritional quality due to the fact that the cows are pasture grazed and also Genetics google books.The major disadvantage is the speculation that these pesticides and resilient genes can pass on to consumers to create u desirable conditions for them such as allergies, diseases and cancer. Though any of these effects are yet to be proven or actually reported, genetically engineered food continues to stock up super market aisles and to be purchased over natural foods. Nowadays, over 65 percent of food items are genetically engineered food or made with popular genetically enhanced components such as corn, rapeseed (canola) or soy. Even though reports exist that laboratory animals that have been fed genetically engineered food have suffered considerable organ damage and illnesses, humans are apparently immune to these effects. But the speculation hasn?t died that it may affect the future generations and their genetic makeup.

Though genetic engineering techniques such as gene splicing of different species or cloning are generally frowned upon by the public as unethical practices that are against the rules of nature, these very procedures can save certain animals from going extinct and from becoming endangered due to manmade effects. The main dangers associated with genetically modified animals and the techniques used to create them are the risks of misuse and the disruption of natural genetic information. Since most modified farm animals are released out to nature, a lot of people are worried that they may cause disru ption to the eco system and the delicate balance of nature with their un-naturally enhanced characteristics. It is considered that with the large amount of genetically modified animals and plants in the world today could lead to the acceleration of genetic erosion, harmful and dangerous mutations as well as the creation of all new diseases that could pose a threat to mankind
