Genetic Modification a Hybrid DNA - Essay Example In case of genetic modification, a hybrid DNA is produced by combining DNA from different organisms. These organisms could be far apart in nature – like producing an organism by combining DNA of dog and cat. In case of non-genetically modified organism natural crossing is done between two different breeds of the same species to produce the combination of the better of the two. This is rather a natural evolutionary process, while the genetic engineering is a completely artificial synthesis of DNA in a test tube. 2. This is possible but this will require the techniques of genetic engineering. To differentiate critically, one requires identifying genes of both the plants. In case of genetically modified plants there will be genes of genes of some other type of plants, while in case of plants modified by molecular genetics, all the genes will be from the same plant. 3. Some relevant examples are - food poisoning, dysentery, nausea or vomiting, obesity, lack of micronutrients, excessive intake of different constituents like iron, allergy, retarded growth etc. All of this can be caused by genetically modified food. But, here I must add a word of caution, all of these can be caused by conventional food as well. The problem is not with the conventional or genetically modified food but is with unsafe food. The only thing that goes in favor of conventional food here is that these are tested and tried since time immemorable, while genetically modified foods are recent phenomena and therefore, some lack of trust is but natural. 4. To answer this we need to go to the basics. For any organism its characteristic is coded in its DNA – be its nutritional composition, shelf life, yield, disease resistance. In case the DNA is suitably modified, these characteristics can be modified. For example, extract a gene resp, possibly for higher yield from a plant and put this into a low yield crop.
