Labels are required for foods where genetic modification has altered the food so it’s nutritional value is outside the average range, the GM produced food has a ‘new factor’ which could cause allergic reactions in some people and when genetic modification raises significant ethical, cultural and religious concerns, regarding the origin of the genetic material.

Biotechnology and Genetically Modified Foods Are genetically modified foods safe? Genetically modified foods are crop plants created for human or animal consumption using molecular biological techniques. These plants have been modified to enhance certain traits like increased resistance to herbicides or improve nutritional content. This process traditionally has been done through breeding, but is not very accurate. Scientists have been using biotechnology to implant the gene that makes the plants act the way they want them to.
Humans do this in order to produce something that will be better or healthier than its original design. One example of such “messing” with nature is genetically modified foods. Genetically modified foods also referred to as GMOs is a term used to describe crop plants designed for human or animal consumption using molecular biology techniques. These crops have been modified in a laboratory by molecular biologists in order to improve some desired characteristics such as enriched nutritional content or better resistance to herbicides. Traditionally, this development of desired characteristics has been done through breeding; however, these plant breeding methods have shown to be very time consuming and not quite accurate.
One of the biggest concerns is that cross pollination will cause the introduced genes to be incorporated into the genomes of other plants. This could result in “superweeds” that are resistant to herbicides and are extremely difficult to eradicate. There are also concerns that bugs could be affected as well. Some believe that there is a possibility that crops transformed with genes that increase pest resistance could harm essential pollinators such as bees and butterflies. On the other hand some fear that pest will become resistant to pesticide that are engineered into crops.
It is used for producing proteins which can be used by humans, such as insulin for diabetics and is also used to make organisms better at surviving, for example genetically modifying a plant so that it can survive in acidic soil. There is debate about whether genetic engineering should be used or not, and to what degree. There are many problems that can occur from the process and many of these cannot be avoided currently. There are known problems and there is also the fact that the whole process is unpredictable and unforeseen problems could crop up. A good example of this was the influence of a genetically engineered organism on a food chain, which sometimes damaged the local ecology.
The Advantages and Disadvantages of Developing Genetically Engineered Organisms Genetic engineering is the method of changing organisms' characteristics inherited by alerting it genetic material. This often done to cause micro organisms, such as bacteria and viruses, to synthesize increased yields of compounds, to form entirely new compounds, or to adapt to different environments. Other uses of this such of a technology, is known as the recombinant DNA technology, it includes gene therapy, which is the supply of a functional gene to a person with a genetic disorder or with other diseases such as acquired immune deficiency syndrome (AIDS) or cancer. Genetic engineering involves the manipulation of deoxyribonucleic acid, or DNA. Important tools in this process are so-called restriction enzymes that are produced by various species of bacteria.
Genetic variation is the raw material for the plant breeder, who must often select from primitive and wild plants, including wild species, in search of new genes. The appearance of new diseases, new pests, or new virulent forms of disease causing organisms makes it imperative that the plant be preserved, because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also, there are demands for new characters-- for example, high protein, improved nutritional factors, and fertility restoration. As a result, plant breeders require a large and diverse gene pool to meet ever changing needs. A gene bank is a popular term that is used to describe repositories for genes of living organisms.
They can also be used to add traits to a plant, that it would not have had otherwise. For example, a plant geneticist could take a gene that produces natural pesticides in one plant, and place this gene inside a different plant, so that it can produce it's own natural pesticides. This particular practice happens to be one of the most widely used method of genetic alteration in crops at this time. Now, this may sound fantastic. But there are also downsides to using GMOs in crop production.
Genetically modified foods also share certain toxic effects on the liver, pancreas, kidneys, and reproductive system that may cause cancer in these organs. The widespread use of recombinant hormones-a genetically modified substance- in the agriculture industry is associated in IGF-1, a growth hormone that, in excess can lead to cancer. GMO foods have many allergy risks to people. Genetic modification often mixes or adds proteins that aren’t native to the original plant or animal, causing new allergic reactions in the body.

GMOs compromise numerous aids to society, including enlarged crop yields and the development of fresh therapeutic agents which prevent and treat a wide variety of human diseases . However there are some concerns around the use of genetically modified organisms which include the risks stood to human health and the initiation of insecticide resistant superbugs. This essay will provide evidence to support the evidence that the genetic modifications of crops produces better results than selective breeding or mutation. The crops have one or more genes coding which have desired traits for insertion. The genes come from the similar or additional plants species or also from unrelated organisms.
