Essay on genetic engineering in food production

What is genetic engineering used for

A GMO is a genetically modified food. In the past, …show more content… The technology has progressed to the point that genes can be transferred from plant to plant and animals or organisms to plants. However, on the basis of infinitesimal theoretical risk, the use of antibiotic resistance genes as markers in GM plants is now strongly discouraged Ramessar et al. One way that the eradication of hunger has been attempted is by increasing the amount of food in the world, so that there is enough to go around. Thus, undesirable genes can be transferred along with the desirable genes and at the same time some genes may be lost in the offspring. On the contrary, as already discussed by Ch. These modified foods and seeds were created with the future of the food industry in mind, yet they have been proven to create harmful effects. What had I done wrong? This includes allergic reactions to possible intestinal damage, many people want to avoid genetically modified foods because of animal studies that have shown changes in internal cell formation, unusual tumor development, and unanticipated passing of life that have occurred, as well as altered the number of cells that regulated the immune system for the body. They are plants or seeds that have been changed genetically by scientist. Scientists modified bacteria to produce chymosin, which was also able to clot milk, resulting in cheese curds.

A review published on behalf of Food Standards Australia New Zealand examined transgenic experimentation on terrestrial livestock species as well as aquatic species such as fish and shellfish. Despite the extraordinary safety record of GM crops, GM agriculture as a whole faces the most restrictive regulatory framework outside the nuclear industry Ramessar et al.

As well, there are alternative protein toxins such as lectins that work against recalcitrant sap-sucking insects; novel approaches include the expression of toxin fusions Mehlo et al.

The two opposing sides argue on the ethical standpoint of the act of genetically modifying plants and animals. Finally, a variety of novel technologies have been developed to control transgene expression, e. A crop could be made to be grow more resistant to bad weather, destructive illnesses, or bugs.

genetic engineering in humans

Certainly the lack of progress in those fields may seem amazing and can be justified only with the fact that the revenues of the leading companies do not come from innovation but from the royalties of already existing GMPs, advertising and stock exchange speculation.

The value of producing such molecules in plants rather than mammalian cells or bacteria as is usually the case is the reduced costs, the better safety profile no human or animal pathogens, no endotoxins and the massive production scale that can be achieved with little additional effort Stoger et al.

By being able to alter their genes into making them grow in a certain way like faster, tastier, and reproduce faster, these modifications allow for the plants and crops to have new varieties of plants and crops that will be formed gradually.

With tax money constantly being spent, we wonder where is all the money going too; one solution is to our foods in are local town stores. When we introduced a single gene encoding C-5 sterol desaturase FvC5SD from Collybia velutipes to the tomato, we obtained a crop with multiple beneficial traits, including improved drought tolerance and fungal resistance [ 715 ].

According to Del Monte's submission, the pineapples are commercially grown in a "monoculture" that prevents seed production, as the plant's flowers aren't exposed to compatible pollen sources. Moreover, epigenomic analyses are not requested, studies on the metabolomes and physiological changes, particularly in hormone patterns, the study of effects on the environment are limited to the possible weed resistance to herbicides, and so on.

Genetic engineering techniques

Christou: The first GM crops on the market were engineered for herbicide tolerance; these were soon followed by plants engineered for pest resistance. In , the European Commission adopted two new legislative proposals on GMOs concerning traceability, reinforcing current labelling rules and streamlining the authorization procedure for GMOs in food and feed and for their deliberate release into the environment. A critical point is that if the EU continues to obstruct GM agriculture, it will force farmers to use environmentally hazardous, expensive and unsustainable agricultural practices, spend unnecessary resources on fossil fuels and agrochemicals, while at the same time importing GM products from the Americas. But before. The farmers cultivate and market the new strain. Such modifications and combinations cannot occur in nature through crossbreeding or by other organic means. Out of these discussions, there is a rising need to do research on genetically modified food verses naturally grown food.

Corn, soy and safflower oil are sources of lecithinthough the majority of lecithin commercially available is derived from soy.
