Genetic engineering is when one gene or a set of a few genes is taken out of the DNA of one organism and then inserted into the DNA of another organism. DNA is what is manipulated by genetic engineering. DNA contains a complete set of information determining the structure and Staples 2 the functions of a living organism and is stored in a long chain. It determines the nature of the organism and characteristics of the particular individual. DNA also contains the instructions for creating all proteins in body.
Genes are individual sections of the DNA chain.
Doing this is very clever and it could be very useful. But, it is all happening too fast and nobody knows what the effects of making such living things will be. Many kinds of life could be changed. There are many various purposes of genetic engineering. These purposes include to repair a genetic defect, to enhance an effect already natural to that organism, to increase resistance to disease or external damage, and to enable the gene to do something it would not normally do.
