Genetic engineering: techniques, benefits and risks

Extracts from this document...

Introduction

Genetic engineering: techniques, benefits and risks David Farrell What is genetic engineering? Genetic engineering is the transfer of a gene from one organism to another. This transfer is from donor to recipient. It is also the scientific alteration of genetic material in a living organism. Genetic engineering is a relatively new and fast moving technology which has the potential for limitless possibilities in influencing the genetic make-up of human genes. However there are certain ethical opposition that genetic engineering has had to face. Genetic engineering involves moving a specific gene from one organism to another, cross breeding however involves moving hundreds if not thousands of genes from one organism to the other. ...read more.

Electro and chemical Poration This technique involves creating small holes in the cell membrane and injection new genes into the hole. This can be done by chemical poration (bathing the cells in special chemicals) or by electro-poration (using a weak electrical currant on the cells). Bioballistics This involves using metal slivers to deliver genetic material to the interior of the cell. A metal plate stops the shell cartridge entering the cell but allows the metal sliver inside to deliver the genetic material. This is usually delivered from a shot gun, once inside the cell it makes its way to the nucleus and assimilates with the host cells. Benefits and risks of genetic engineering A very popular benefit of gene therapy is the possibility that genes which have defects ...read more.

Conclusion

Also if a specific virus is created which only targets the genetically engineered crop then entire crops will die and thousands of people will go hungry and die. In my opinion I think that gene therapy is very advantageous but it needs to be altered to reduce or eliminate certain risks to consumers. An American scientist's report published in the New York Times states that genetically engineered crops do not pose unique risks, that the same risks can be found in crops grown with conventional breeding methods. This shows that scientists on both sides of the argument have pros and cons, however until a genuine life threatening reason can be found genetically engineered crops may be one of the only ways for third world countries to sustain their economy and to feed its people. ...read more.

    This aspect of genetic engineering applies not only to altering embryos but to all branches of biotechnology. Consider genetic screening, for instance. "...What if the couple (or the government) is permitted to monitor embryos so that any with an Ôundesirable' genetic trait may be aborted?

    She had opened many new windows of opportunity for scientists who hope to soon be able to clone humans using the same technology. The possibilities really are endless. A single cell from an elite racehorse could be used to create hundreds of identical copies, each with the same elite genetic makeup.

    The beneficiaries of these new enhancements will include: * Farmers - higher yields; less use of pesticides and herbicides; plants that can withstand adverse conditions ( salinity, drought, temperature variations); better shelf life; higher prices for crops that provide higher nutritive content.

    This rice has been called 'Golden Rice'. The people in the third world are also taught how to grow GM foods such as the Golden Rice, and crops that are salt and drought-resistant. It could enable farmers, for example, in Africa to grow crops in areas where it has previously been impossible to do so, making it easier for local agricultural schemes to flourish.
