Genetic Engineering Examples Show What Is Possible

Genetic engineering examples are found in agriculture, with both plant and animal life being culture grown to be more useful to the farmer and the eventual marketplace, although it is the plant side of agriculture which is far more advanced and developed. There are also examples of genetic engineering in human medicine, so far with mixed but largely promising results. There have been actual cures of immune system disorders, although there have also been cases of leukemia which have been caused by the technology as side effects.

The most common examples of genetic engineering are those found in crop agriculture, which are largely aimed at reducing losses of the crops due to pestilence and over use of chemicals. This is only the first generation of techniques, and there is also the possibility of using genetic engineering to directly counter natural phenomena such as extreme cold and drought. This could dramatically increase crop yields over a number of years. Genetic engineering in plants can also be used to produce supplies of drugs and vaccines more cheaply than is possible using conventional techniques. Some of these technologies are already in commercial use in the developed world, while others are still being refined.

The use of genetic engineering in animals is lagging far behind in terms of its development and its readiness to be used in the commercial market. There is a potential for farm animals to be grown to a bigger size so that more meat can be produced from the same size of herd and the same use of acreage, but the same effect can be achieved with growth hormones which are far cheaper. The likelihood is that this technology will be usable in the future, but only as a side effect of other technologies as the expense of developing it alone would be prohibitive.

types of genetic engineering

There are also some more extreme and dubious genetic engineering examples using farm animals, aimed at purposes which are highly controversial even among those who support genetic engineering as a principle. These include growing animals which are made to be more human in form, so that they can be used to test drugs on. These drugs would normally be tested on human volunteers first, with the inevitable possibility that there will be some bad reactions and possibly some casualties as well. If drugs are tested on animals first, those which cause serious reactions can be eliminated before they are ever used on humans.

It is even possible to genetically engineer animals with more human features so that their organs can be used in transplants to replace human organs. A typical example is to transplant the heart of a pig to replace a human heart, and this would be almost certain to fail if it was carried out with the heart from a naturally occurring pig. This type of operation is one of the most extreme and controversial uses of genetic engineering which has yet been thought of, and only time will tell whether it becomes part of established medical practice or not.

genetic engineering

These genetic engineering examples do not represent the full extent of what the technologies are capable of, but they do illustrate what is possible and what scientists are currently working on. Only the future will tell us how many of these plans ever come to fruition, or how many create so many unpleasant side effects that they have to be abandoned. It is clear that there are many year of research ahead for those who believe in genetic engineering, and who seek to realize these and other genetic engineering examples.
