Introduction

Welcome to my informative blog!!

Objectives of the blog are to educate user the definition of genetic engineering, the uses of the technology and the controversial issue that occurred in developing this technology. This blog also emphasize the advantages and disadvantages of Genetic Engineering.

Brief descriptions of the topic are:

Definition

The manipulation of an organism genome using biotechnology.

 The uses of Genetic Engineering

·         For medical Purpose

Has being used to treat many diseases(diabetes, vaccination)

·         For agriculture uses

Genetically modified of a crop to adapt with environmental changes.

  Controversy issues

·         Involve animal testing. Been debated by people who are concerning on animal rights.

·         Most of religion agreed modification of human genetic should be banned.

·         Some researchers believe Genetic Engineering may cause cancer or tumour.

  Advantages

·         Help people to gain new knowledge about science.

·         Treat new medicine for chronic disease.

·         Increase the diversity of species.

   Disadvantages

·         May cause moral issues.

·         May cause mutant of some species.

·         It is a complex research and time consuming.

Disadvantages of Genetic Engineering

In the context of applications of genetic engineering in human life, misuse of this technology in the production of biological warfare or weapons is a very major disadvantage.Genetic engineering is being used to create human organs but in the long run if it can create genetically modified, perfect human specimens who are better than the creators than this may be disastrous. Nature selection in man and the resulting diversity of the human genetic pool is essential for the survival of the species. Genetic engineering will interfere with this process too causing unknown complications. Last but not the least in this long list of disadvantages of genetic engineering are the ethical and moral objections which religion has to these techniques. For example, the use of stem cells obtained from unborn human fetuses created and destroyed for this very purpose is unethical in the eyes of religions.

It is obvious from the given list of disadvantages of genetic engineering above that there is need to proceed with caution in use and the absolute necessity of creating as well as enforcing ethical legislation to prevent misuse also.

worker say no to Genetic Engineering!

Benefits of Genetic engineering

Because of new development of science, Genetic engineering has its own advantages; disease could be prevented by detecting people/plants/animals that are genetically prone to certain hereditary diseases, and preparing for the inevitable. Also, infectious diseases can be treated by implanting genes that code for antiviral proteins specific to each antigen. Animals and plants can be 'tailor made' to show desirable characteristics. Genes could also be manipulated in trees for example, to absorb more CO² and reduce the threat of global warming. Genetic Engineering could increase genetic diversity, and produce more variant alleles which could also be crossed over and implanted into other species. It is possible to alter the genetics of wheat plants to grow insulin for example.

genetic engineering may produce good genome of agriculture products.

Controversial Issue of Genetic Engineering

Genetic engineering has always been a controversial topic, but, it seems a relatively recent one.

This approach question using two applications of genetic engineering as lenses: genetically modified food and other living organisms. Organizations such as Greenpeace are vehemently against the use of genetically modified organisms for two reasons. First, they fear that the genetically modified organisms will integrate themselves with organic organisms, producing new forms, and thereby permanently changing the environment. They also cite that there is too much unknown about the effects of genetic engineering to safely apply to our food sources. 
Secondly, they fear that production of genetically modified foods is merely a means through which business entities can experiment with and exploit our food supply for profit. However, experiments in 1987 by the Committee of the National Academy of Sciences have already concluded that genetically modified food posed no risk of damage to the environment. These experiments on tobacco and tomato were preceded by the engineering of bacteria to create insulin and interferon in the 1970's.
