Commercial potential of biotechnology is immense since the scope of its activity covers the entire spectrum of human life. The most potent biotechnological approach is the transfer of specifically constructed gene assemblies through various techniques.

You've probably heard the term "GMO" before, but what does it mean?

Genetically modified organism

Genetic modification is a special set of gene technology that alters the genetic machinery of such living organisms as animals, plants or microorganisms. The principal transgenic crops grown commercially in field are herbicide and insecticide resistant soybeans, corn, cotton and canola. There are bananas that produce human vaccines against infectious diseases such as hepatitis B, fish that mature more quickly, fruit and nut trees that yield years earlier and plants that produce new plastics with unique properties. Technologies for genetically modifying foods offer dramatic promise for meeting some areas of greatest challenge for the 21st century. Like all new technologies, they also pose some risks, both known and unknown. Controversies and public concern surrounding GM foods and crops commonly focus on human and environmental safety, labelling and consumer choice, intellectual property rights, ethics, food security, poverty reduction and environmental conservation. This review will also address some major concerns about the safety, environmental and ecological risks and health hazards involved with GM foods and recombinant technology.

In this chapter, the committee examines the evidence that substantiates or negates specific hypotheses and claims about the health risks and benefits associated with foods derived from genetically engineered GE crops. There are many reviews and official statements about the safety of foods from GE crops for example, see Box , but to conduct a fresh examination of the evidence, the committee read through a large number of articles with original data so that the rigor of the evidence could be assessed. Some of the evidence available to the committee came from documents that were part of the U.

Meanwhile, cultivation of GMOs remains forbidden in over thirty nations. In , a majority of European Union countries decided to block the cultivation of eight new types of GMO pending new data and approval from regulatory bodies. Nonetheless, the European Union remains the greatest user of GMOs: 30 million tonnes of genetically modified soya beans and corn are required for animal feed every year. In most cases, farmers who use GMO technologies do so to increase productivity, either by increasing production yields minimising pest-related losses , or financial returns reducing labour or the use of specific phytosanitary products. Although these solutions have obvious appeal for agricultural production, their opponents emphasise that uncertainties persist as regards to their environmental impact. They cite, amongst others, the possibility of transferring genes to other species, the excessive use of certain phytosanitary products, and the consolidation of intensive cultivation at the expense of other more sustainable approaches. The issue remains open and is still debated at most governmental and inter-governmental levels.

Genetically Modified Foods and Social Concerns

Genetically modified organism GMO , organism whose genome has been engineered in the laboratory in order to favour the expression of desired physiological traits or the generation of desired biological products. In conventional livestock production, crop farming, and even pet breeding, it has long been the practice to breed select individuals of a species in order to produce offspring that have desirable traits. In genetic modification, however, recombinant genetic technologies are employed to produce organisms whose genomes have been precisely altered at the molecular level, usually by the inclusion of genes from unrelated species of organisms that code for traits that would not be obtained easily through conventional selective breeding. A genetically modified organism GMO is an organism whose DNA has been modified in the laboratory in order to favour the expression of desired physiological traits or the production of desired biological products. Genetically modified organisms GMOs provide certain advantages to producers and consumers. Modified plants, for example, can at least initially help protect crops by providing resistance to a specific disease or insect, ensuring greater food production. GMOs are also important sources of medicine.

Objective To research and debate the arguments for and against the use of genetically modified foods. The issues of the safety of and need for genetically modified foods are being hotly debated in the United States, Europe, and other countries. To help students understand this complex issue, tell them they have been appointed to brief a special Food and Drug Administration review board about the pros and cons of genetically modified foods. How these foods are different, and how they are the same, as other products currently being sold. Organize students into groups, based on whether they took notes for or against the use of genetically modified foods.

The debate over the environmental impact of genetically modified GM crops is growing increasingly complex, intense, and extremely emotional. It is further complicated as new research is published. Are GM crops safe for the environment? Assessing the environmental impact of GM crops is often difficult as many factors are considered.

Scientists take the gene for a desired trait in one plant or animal, and they insert that gene into a cell of another plant or animal. Genetic engineering can be done with plants, animals, or bacteria and other very small organisms.

Risks and Precautions of Genetically Modified Organisms

Беккер понял, что ему следовало заранее отрепетировать разговор, прежде чем колотить в дверь. Он искал нужные слова. - У вас есть кое-что, что я должен получить. Эти слова оказались не самыми подходящими. Глаза немца сузились. - Ein Ring, - сказал Беккер.  - Du hast einen Ring.

 Да. Он вызвал скорую. Мы решили уйти. Я не видела смысла впутывать моего спутника, да и самой впутываться в дела, связанные с полицией. Беккер рассеянно кивнул, стараясь осмыслить этот жестокий поворот судьбы. Она отдала это чертово кольцо. - Я пыталась помочь умирающему, - объясняла Росио.

Сьюзан представила себе, что пришлось пережить коммандеру, - весь этот груз бесконечного ожидания, бесконечные часы, бесконечные встречи. Говорили, что от него уходит жена, с которой он прожил лет тридцать. А в довершение всего - Цифровая крепость, величайшая опасность, нависшая над разведывательной службой. И со всем этим ему приходится справляться в одиночку. Стоит ли удивляться, что он находится на грани срыва?.

Она не могла понять, что задержало его так надолго. У ее ног лежало тело Хейла. Прошло еще несколько минут.

 Soy Hulohot, - произнес убийца.  - Моя фамилия Халохот.  - Его голос доносился как будто из его чрева. Он протянул руку.

Я понимаю, ты расстроена из-за Дэвида. Я не хотел, чтобы ты узнала об этом. Я был уверен, что он тебе все рассказал.

    Genetically modified foods GM foods , also known as genetically engineered foods GE foods , or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
