What are genes All living organisms are made up of millions of cells that contain DNA, DNA is made of genes which give an organism its characteristics. The combination of DNA of both parents gives the child’s hair colour, it is the same in parent plants there DNA determine the characteristics of the offspring such as size and colour etc. What is selective breeding? Changes made to a gene may change the characteristics of a plant or animal. In society today there is a high percentage of our food is changed in some way today of the food we eat. For years people have been selectively breeding crops to produce higher yields or greater disease resistance. Various fruit and vegetables that we eat today were not available years ago. What is genetic engineering? Scientist discovered how to alter and single out certain genes. This means that they can transfer genes to another organism which in turn makes it possible for scientist to “engineer” the characteristics of that organism to produce a new variety. This method is now used in production of medicine, pharmaceuticals and now genetically modified plants and animals. What is genetically modified food? Genetically modified foods are foods produced from organisms where there genetic makeup was altered specifically by using the methods of genetic engineering. The term genetically modified foods is mostly used to refer to plants created for human or animal consumption using genetic engineering. The plant’s DNA is changed to enhance specific traits such as increased nutrition Genetic engineering, makes it possible to create plants with the desired traits with very little time need with great accuracy. Plant geneticists can isolate a gene in one plant for the resistance of drought and insert i... ... middle of paper ... ... this • Pharmaceuticals - Medicines and vaccines often are very costly to make and sometimes they need special storage conditions that would not be available in third world countries. Researchers are working to develop edible vaccines in tomatoes and potatoes. If this is possible it would be much easier to ship, store and administer than injectable vaccines.. Disadvantages Environmental activists, religious organizations, public interest groups, professional associations and other scientists and government officials have all concerns about genetically modified foods, and criticized agribusiness for trying to gain profit without taking into consideration the potential hazards. It appears that everyone has a strong opinion about modified foods. Most concerns about GM foods fall into three categories: environmental hazards, human health risks, and economic concerns.
