Biotechnology can be defined as the application of a new technology to the research and development of products from plants and animal cells. Since biotechnology has a broad scope it has an equilibrium range of concerns. However continued research offers many possibilities to the development in the field of biotechnology. Throughout history, humans have selected particular plants for cultivation as crops because they may be edible, produce good fibers, contain useful chemicals or have a high rate of photosynthesis. A plant that has a high rate of photosynthesis has a high rate of productivity. In this way crops have steadily improved. This process is called artificial selection, which is to select alleles for characteristics which are agriculturally valuable. Today scientists are able to put new traits into a plant which was previously unavailable. For example, there are fishes that survive at very low temperatures and these genes have been taken and have been transfe...
