INTRODUCTION Genetically modified foods (GM foods or biotech foods) are foods made from genetically modified organisms (GMOs)‚ specifically‚ genetically modified crops. GMOs have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective

Summary of three articles A. GMO FACTS What are GMOs? - Genetically modified organisms are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering‚ or GE. - This relatively new science creates unstable combinations of plant‚ animal‚ bacteria and viral genes that do not occur in nature or through traditional crossbreeding methods. - To withstand direct application of herbicide and/or to produce an insecticide. - GMO is accompanied by

What is GM food? Genetically modified food (GM food‚ or biotech food) refers to any food or food ingredient that is‚ or is derived from‚ an organism in which the genetic material has been modified using modern biotechnology. How does GM food be produced? Nowadays‚ scientists can identify and modify genes controlling specific characteristics using modern biotechnology. They use a variety of biotechnology‚ such as biochemical "scissors" to cut the DNA sequence at a specific place‚ and then select

Introduction: “Genetically modified (GM) foods are food items that have had their DNA changed through genetic engineering.” (Mavis 2008). As the population of the world has continued to grow‚ the supply pressure of food has become more and more significant. With the development of Genetically Modified biotechnology‚ GM Foods have been come into our daily lives. Though GM foods can help to improve the quality of life‚ there are risks to complete trust in GM foods. What’s more important‚ a part of

already have been approved. GM salmon is‚ as we speak‚ on its way to our dinner table. Wild salmon matures slowly‚ taking up to three years to reach its full size. GM salmon‚ on the other hand‚ not only will grow faster but also should reach about twice the size of its wild cousin. The creators of the GM salmon‚ a private company called AquaBounty‚ promises to harvest the salmon before it reaches its full size‚ thus preventing "giant" versions [source: Discover Magazine]. The GM salmon‚ known as AquAdvantage

benefits‚ there are still several safety issues towards genetically modified foods. As for human health‚ the concerns for safety‚ allergenicity‚ toxicity‚ carcinogenicity‚ and altered nutritional quality of food are controversial. Due to the fact that GM contains the transfer of genes that may code for proteins not normally present‚ which means there exist unknown character will be more or less allergenic than their conventional

The 21st century has presented a major set of converging threats as the pressures of population growth‚ climate change and food insecurity are driving the world towards worsening hunger and malnutrition. Many people argue that Genetically Modified (GM) crops are promoted as a ‘Miracle Solution’ to solve the food shortage crisis since the use of genetic engineering enables genetic materials to be modified and in turn creates new varieties that exhibit desirable characteristics such as resistant to

The Help of GM Crops Norman Borlaug was one of the most influential individuals that no one has ever heard of. His genetic research in Mexico‚ India‚ and Pakistan led to the creation of disease resistant‚ high-yield crops that saved more lives from starvation than the number of those lost in both world wars combined. His pioneering work earned him a Nobel prize in 1970 along with the title‚ “The Man Who Saved a Billion Lives” (Wilson). Scientists have since expanded his research into the field of

INTRODUCTION General Motors Company (GM) is known as one of the world’s top automakers that do business in more than 157 countries. By providing quality vehicle security‚ and information services‚ GM is always listed as one of the best choices that customers from different ages and social classes tend to pick. But recently‚ due to poor management decision‚ the recession of 2008‚ and its inability to be flexible to change and the loss of market share to foreign competitors‚ GM filed for Chapter 11
