| وصف الكتاب | Genetically modified foods are foods derived from genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. The main aim of genetically modified crops is to produce a food that is able to survive even if any harmful chemicals or pesticides or herbicides are sprayed. Genetically engineered foods have had their DNA changed using genes from other plants or animals. Scientists take the gene for a desired trait in one plant or animal, and they insert that gene into a cell of another plant or animal. Genetic engineering can be done with plants, animals, or bacteria and other very small organisms. Genetic engineering allows scientists to move desired genes from one plant or animal into another. Genes can also be moved from an animal to a plant or vice versa. Genetic engineering also helps speed up the process of creating new foods with desired traits. Genetically modified material sounds a little bit like science fiction territory, but in reality, much of what we eat on a daily basis is a genetically modified organism. Whether or not these modified foods are actually healthy is still up for debate—and many times, you donâ€t even know that you are buying something genetically modified. The book will be of help to researcher in the field of agriculture, crop improvement, biotechnology etc. It will also be helpful to teachers and students for better understanding of the subject. |
