The manipulation of an organism’s genetic arrangement using modern DNA technology is known as genetic engineering or genetic modification. Following this definition of genetic engineering, one could say that an organism’s structure is altered by introducing genes which are foreign to what nature has dictated that particular organism to have. A particular genetic sequence is copied and reproduced using a method known as molecular cloning, after which that particular is sequence is introduced into another organism. When this happens, the organism that has been produced is said to be a genetically modified organism or a GMO.
You’ll Be Shocked When You Find Out The Number Of Bad Examples Of Genetic Engineering
Some examples of genetic engineering involve the manipulation of the genetic structures of agricultural crops. The basic structure of a certain vegetable or fruit is modified and given extra characteristics which are otherwise not common to the said crops. Amongst the different examples of genetic engineering that has been developed, one particular example would be crops developed to address the problem of excessive pesticide use by farmers. Crops were introduced with a protein called Bacillues thuringiensis. This particular protein made crops resistant to pests thus lessening the need for pesticides. Another particular crop that been genetically modified is rice. A new variant known as golden rice is genetically modified. This rice has been fortified with vitamin A and iron to address the need for these particular nutrients in developing countries whose main staple is rice.
Define GMO To Protect Public Welfare
In order to define GMO, one has to look into the processes involved behind genetic engineering. As previously mentioned, a specific gene sequence from one species is isolated and reproduced. This step is called molecular cloning. There are many steps involved in molecular cloning such as the use of antibiotic resistant genes and cultures in order to isolate a specific gene sequence. Once isolated, this specific gene sequence is then introduced to the organism which needs to be modified. The new variant that results from these genetic manipulations is known as the genetically modified organism. To define a GMO, it can be said that a GMO is any particular organism whose genetic makeup has been tampered and altered with in order to produce a different breed of that particular organism.
Genetic engineering has found its way into many aspects of daily living. Besides agricultural crops, genetic engineering has found its way into animals as well. Some fish, for example, have been genetically altered to make them more resistant to disease thus addressing the need for food in different parts of the world.
For medical purposes, genes have been cut, created and combined and introduced into the human body in order to correct whatever malfunctions there are in an individual. A case in point would be the introduction of insulin genes produced from healthy donors into the body of diabetics.
Although genetic engineering has some advantages, it is important to note that the effects of this technology on a larger scale are still highly unknown. It is a comparatively new technology whose results are yet to be discovered in the years to come.
