Genetic modification is the process of changing an organism’s genes to alter its characteristics. The aim is to add a trait that is not already found in that organism. Some enzymes can cut a useful gene from one organism’s chromosome and cut another organism’s chromosome to insert the gene. All organisms use the same language of DNA, so a gene from a human can be removed and placed in a different organism and it will still carry out its function.
Using genetic modification to treat illnesses, especially genetic disorders and cancer, is called gene therapy. This involves cutting out the normal allele using certain enzymes, making many copies of the allele and then inserting them into the cells of the person who has the genetic disorder. However, it is not always successful as the alleles may join with the chromosomes in random places or the alleles may not go into every target cell.
There is a possibility that genetic modification can treat cystic fibrosis by replacing the genes in the people that have the disorder with working genes. In addition, genetic modification used to treat HIV could prevent it from evolving into AIDS by creating cells that are resistant to the two major types of the virus.
People in developing countries lack nutrients in their diets, so crops can be genetically modified to contain more nutritional content. For instance, ‘Golden rice’ (normal rice which has been modified to contain beta-carotene) is being tested. Lack of vitamin A kills around 2 million people every year in developing countries, and is a major cause of blindness. Giving this rice to people in developing countries is a simple way to boost their vitamin A levels.
Genetic modification can be used to transfer desirable genes into plants at their early stages of development so that they will develop those useful characteristics.
Genetically modified plants are usually made to produce a higher yield, be tolerant to cold and drought, improve taste and nutritional content and be resistant to herbicides (weed killers), insects and disease. Although genetically modified crops are not being grown in the UK, they are already being grown around the world without any problems.
However, genetically modifying foods is a controversial topic. Their safety and

Crops As the world’s demand for food continues to increase plant breeders work to breed better yielding crop varieties. They use a range of methods including conventional breeding, mutagenesis, genetic modification, and marker aided selection to breed new improved crop varieties. Genetic modification allows plant breeders to produce a crop variety that could not be bred using conventional breeding Genetically modified foods are foods derived from organisms whose genetic material (DNA) has been modified…
implications Tyler Collins Genetic modification is the process by which an organism, plant or animal has had its genetic material changed in a process that does not occur naturally. The process works by either isolating a gene of an organism and joining it with the genes of another organism or by altering the already existing DNA in order to produce a desired quality in the organism or to gain more insight into genetic technology.(Phillips, T. 2008)( What is genetic modification? 2007) A genetically…
Crops in Australia. The report includes a brief introduction of how the GM Crops produced. This essay will not examine the rules of labeling GM Crops in other countries. Moreover, future development of Genetically Modification will not be included. The development of genetically modification using in other organisms, like sheep and cow, are also beyond the scope of this report. 2. Procedure A number of primary and secondary resources were used in this research report. These are including…
Genetic engineering is the process of adding and altering new DNA (genetic material) to an organism so that the organism has specific characteristics. A few examples of genetic engineering is cloning ,pesticide resistant rapeseed oil which is a flowering plant used to make certain types of vegetable oil. Genetic engineering has allowed these plants to be resistant to certain types of pesticides, so that when the fields are treated to remove pests, the plants will remain unscathed. Golden rice is…

Ugly Genetically modified (GM) foods are rising as a new contender to the good ol’ natural crops we have known and loved for all of human history. No longer are we satisfied with having a sufficient amount of food, we want a surplus, and how do we plan on getting that? Genetic modification! All of these procedures attempt to create superior crops which can withstand all pests, weeds, pesticides and can end world hunger. Scientists construct these “super-foods” by taking the genes from one organism…
666). The aims of organic farming are, to decrease pollution, maintain soil fertility and biodiversity, be more sustainable, and have increased nutritional benefits than conventionally grown foods (Yaping et. al., 2003, p. 298). While the aim of conventional farming is to provide safe, proficient supplies of food, in abundance and at low prices (Trewavas, 2001, p.409). Since 1996, the amount of land in the UK dedicated to organic farming has risen tenfold (Adam, 2004, p. 666). As well, from 1992 to…
Genetically Modified foods have been an unavoidable spotlight in the news lately. More specifically, GMO labeling has been the focus of a lot of the buzz going around. Genetically Modified foods held a lot of promise to efficiently and affordably feed households around the nation for a fraction of the cost as GMO-free foods. Many years later when the initial excitement died down, environmental organizations and public interest groups have been actively protesting against these GM-foods. Questions have…
New kinds of foods called genetically modified organisms, also known as GMOs, has been creating concerns in the American market for the past several years. Scientists today are able to produce new foods by transferring genes from one organism to another. This technique has been developed to improve the shelf life, nutritional content, flavor, color, and texture of foods. While true, people argue that Organic foods are healthier and more beneficial to the human body and the planet than GMOs. Organic…
Franklin Bushey Research Paper Genetic Engineering Will Play a Dominant Role in Relieving the Effects of Global Warming. Among the devastating natural disasters the world has faced thus far, environmentalists are anticipating global warming to have the greatest catastrophic impact on the world. Global warming is due to greenhouse gases such as carbon dioxide, water vapor, nitrous oxide, and methane that trap the sun's heat in the earth's atmosphere. This phenomenon is known as the "greenhouse…
