Hire Writer Ina doctor from Aberdeen, in Scotland, published results from a research study he conducted suggesting that genetically modified potatoes, injected with an insecticide gene from the snowdrop plant, were toxic to rats. A year later it was announced that beginning inthere were to be trials of genetically modified crops engineered to be resistant to herbicides.

The purpose of the trials was to uncover the effects of these crops on farmland wildlife. However, this was criticized to be potentially dangerous to nearby crops, as well as honey that could be affected by cross-pollination. Sure enough, later that year pollen from genetically modified oilseed rape, a plant that is used to produce canola oil, was found at beehives almost three miles away.

Two out of nine samples of honey being sold in supermarkets were contaminated in May At this point in time, nine out of ten people were against the idea of genetically modifying foods.

Despite the controversy surrounding genetically modified plants and foods in earlier years, technologies have advanced, and in Soybeans, corn, cotton, canola, and alfalfa were modified to be herbicide and insect resistant, whereas other crops, like sweet potatoes for instance were modified to be able to survive harsh weather conditions.

The process of genetic modification Genetically modifying foods changes their genetic makeup in some way. The purpose of doing this is to enhance certain aspects of the food, for example, increasing its resistance to herbicides or its nutritional value.

Traditionally, this has been done by way of selectively breeding plants or animals for specific genetic traits, however this method has proven to be potentially inaccurate and very time consuming. Genetic modification on the other hand can physically isolate a particular gene and insert it into another substance, enabling it to then posses that quality.

This is done very quickly and accurately. Plants can be made insect resistant, virus resistant, or more tolerant to herbicides. Bacillus thuringiensis is a bacterium that produces a gene for toxin production that is safe for human production.

To achieve insect resistance, the gene is injected into the crops that will then be able to produce this toxin on their own, leading to a decreased need for insecticides. To achieve virus resistance, crops must be introduced to the gene from that particular disease-causing virus.

This results in less susceptibility to the disease and higher crop yields. Similarly, to achieve herbicide tolerance, a gene from a bacterium that will transmit resistance to some herbicides must be injected into the crops, in turn reducing the amount of herbicides used.

Purpose of genetically modifying foods There are many reasons for producing and selling genetically modified foods over those that are traditionally produced. Originally, the intent was increased protection of crops.

Both consumers and producers who feel that genetically modified foods are advantageous believe that these foods can be cheaper, more durable, and more nutritional. Genetically modifying foods is also a way to ensure that with a world population that is predicted to double in the future, a food shortage will not be encountered.

In addition to increased protection from diseases, pests and herbicides, there are other key reasons for genetic modification. Many crops are destroyed due to troubling weather conditions.

Frost can come at unexpected times causing destruction to sensitive crops.Vitamin A deficiencies are widespread in the developing world. Some countries like Sri Lanka plan outright bans against the importation or planting of recombinant crops, whereas others like India are attempting to develop their own biotechnology industry and are relatively receptive to recombinant crops (Johnson-Green, , p.

17). Genetically modified crops (GMCs, GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques.

In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species. On the other hand, some people wonder if GM foods are safe and healthy to eat. Genetic engineering is a relatively new development.

As a result, research on the long-term health effects of GM. The best known example of this is the use of B.t. genes in corn and other crops. B.t., or Bacillus thuringiensis, is a naturally occurring bacterium that produces crystal proteins that are lethal to .

Genetically modified organisms, also known as GMOs, make up for majority of the foods being produced today. There are a few to no benefits to these altered and ‘fake’ organisms.

GMOs are organisms that have had their gene material altered by a process called genetic engineering. We will write a custom essay sample on Genetically Modified Foods specifically for A year later it was announced that beginning in , there were to be trials of genetically modified crops engineered to be resistant to herbicides.

Soybeans,, corn, cotton, and rapeseed oil are the most commonly genetically modified foods. In other.
