Out of the all the options available to solve this predicament, people most often resort to the application of genetics addressing it as the sole panacea of the dilemma because it is convenient, relatively low in expense and efficient.
The obvious benefits would be a ready supply of organs not dependant on the death of a healthy person as well as advance preparation time for the transplant to minimise the risk of rejection.
This problem would be worsened if fast spreading diseases were used - without treatment whole populations could disappear in very little time.
In addition, the resources saved in such forms of meat production could be used elsewhere for human benefit. However, one of the perhaps most dangerous risks of the new advances is their undeniable potential for biological warfare.
If then the organism encounters a change without the gene which would have made adaptation possible, it could suffer or even perish. Surely with advances at this rate, these visions of the future of genetic engineering are not as far off as I would like to think.
This technique is beneficial in the treatment of cancers and lung, blood and liver disorders. The year marked the dawn of a new era in both genetics and the food processing industry when the Flavr Savr tomato which lacked the protein for ripening hit shelves McLean.
An example of another controversial but popentially beneficial form of genetic engineering is the alteration of pig DNA to suit human immunology.
Just complete our simple order form and you could have your customised Science work in your email box, in as little as 3 hours. Why have an average child, when it is possible to have one with perfect health, good looking, intelligent and matching every other desirable characteristic which parents could want?
Search our thousands of essays: This method of food production has over the past few decades become so widely practiced that a significant amount of nutriment is obtained through the consumption of genetically manufactured food items. A particular retrovirus has been discovered which, harmless to pigs, has the potential to cause severe ill effects in humans.
All the previously mentioned applications of genetic engineering have had clear benefits to the human species in spite of equally apparent risks.
Despite the extensive intake of genetically modified food in our diet, they are detrimental to human health and the environment. Genetic testing is also useful for families in which autosomal recessive disorders are known to exist, when these are planning to have children.
On the other hand, the benefits to humans are obvious where gene replacement has been successful in improving aspects of food production. This potential for engineering deadlier and more resistant infections or diseases scares all nations. For example, production costs can be lowered and health, taste and look of a product maximised.
Somatic cell therapy, for example, uses faulty genes to target the affected areas for genetic treatment. Equally, a lot of food shortage problems in the Third World could be solved by adapting crops to grow in such harsh conditions.
Weapons could now be directed at the water supply or even crops grown by the enemy. Knowing that your life may be short could inspire you to make the most of it while it could equally well cause severe depression. Individual choice decides whether a person would rather know if they are particularly vulnerable to certain diseases or more likely to die young.
Heineman Oxford - J. Be it livestock or crops, the alteration of genes, for example to boost growth, could have side effects such as weakening resistance to a particular disease. These advances in genetic engineering make the possibility of "designer babies" a reality.
Similarly, the inserted gene may have other functions that are not known about. Some of the effects of these unknown gene functions may be noticed immediately and possibly be rectifiable, while others without immediate effect may cause significant long term changes. By changing other common diseases, an antidote could be found to vaccinate allied populations while only the enemy would suffer.
Such problems may be cumulative and become harder to stop through time as the spread of new genetic problems continues through generations. A more controversial technique is the genetic alteration of gametes which causes a permanent change for the organism as well as for subsequent generations.
On the larger scale of life, natural variation is vital for subtle adaptions that help species accommodate to changing environments. Of course if the gene is corrected without further negative effects, the genetic disorder has been successfully eliminated; but if a problem arises it could pass on.
How far this could go, is unpredictable; theoretically humans could for example be made more efficient - requiring less food but able to work harder. They assured us that they based all their decisions on peer-reviewed science.
Strains of pathogens could be tailored to the enemies strain of livestock or crops, starving a nation into surrender. If genetic alterations become widespread, genes required for particular circumstances or different environments that may be encountered by the organism, could conceivably be bred out.
However, one of the problems with changing the structure of human DNA, is the subsequent loss of natural variation. There are UK writers just like me on hand, waiting to help you.Genetic Engineering Essay Words | 4 Pages Genetic Engineering Many scientists today are all trying to prefect the studies of genetic engineering, also known as cloning.
Genetic engineering otherwise called genetic modification and can basically be described as the ‘direct manipulation of an organism’s genome’ which is the complete set of genetic material of an animal, plant or other living thing. Essay: Genetic engineering Genetic engineering is a technique involving the manipulation of an organism’s genome through the insertion of a gene, removal of a nucleotide sequence or alteration of a gene’s ability to express itself.
Genetic Engineering and the Media Essay Genetic engineering and its related fields have stimulated an extremely controversial scientific debate about cloning for the last decade. With such a wide range of public opinions, it is hard to find any middle ground.
Genetic Engineering Essay - Genetic Engineering GENETIC ENGINEERING Within a short period of time, genetic engineering has turned into one of the biggest growth areas in scientific ultimedescente.com appears regularly in the media although the general public have no idea the meaning.
Genetic Engineering Essay. Genetic Engineering: Designer Babies What if the world were free of genetic diseases, or if it was a place where parents could control their offspring’s height, hair color and intelligence?
The science may be closer to being available then some people think.Download
