Genetically modifying seeds to produce herbicide-resistant plants that increase crop yields has revolutionized modern agriculture. However, genetically modified organisms (GMOs) have come under fire in recent years, with consumer groups calling for mandatory GMO labeling on all food packages that contain GMO ingredients. GMO labeling laws have been in force in the European Union and other countries for several years, but the threat to the U.S. food industry is only now surfacing. Although bills requiring GMO labeling have been introduced in many state legislatures, Vermont is the only state where such a law has so far withstood the first round of legal battles from the industry. Leading chemical companies, including Monsanto, BASF, and DuPont, are the world’s largest suppliers of seeds that grow the food that feeds the world. To counter the GMO labeling threat, they now are turning to mutagenesis as an alternative technique to create herbicide-resistant crops. Mutagenesis mimics the…

- In Genetically Modified or GM, What are the main issues of concern for human health?arrow_forwardAre Genetically Modified Foods Safe?arrow_forwardAquAdvantage salmon is a genetically modified (GM) Atlantic salmon developed by AquaBounty Technologies. The Food and Drug Administration (FDA) has approved the company's application to allow the entry of this GM salmon into the United States food supply late last year. The FDA announced that: "AquAdvantage salmon is as safe to eat as any non- genetically engineered (GE) Atlantic salmon, and also as nutritious." However, opponents of genetically modified food are claiming that the AquAdvantage salmons could pose a serious environmental risk to the marine ecosystem if the engineered fishes escape from the farms. These transgenic salmons would be a big threat to the wild salmons. Justify this statement.arrow_forward
- Describe some of the main techniques used in biotechnology to genetically modify food.arrow_forwardOkay, maybe GMOs have decent uses but it can't all be good. I've heard all of the following about GMOs. Which ones are realistic concerns? select all that applys a)Some GMO are patented and farmers must buy seeds every year rather than saving them from their crops. b)GMO's cause allergies at a greater rate than crops produced by cross-breeding. c)Inserted genes produce amino acids not found in nature. d)Inserted genes may escape into wild plants near farmed fields.arrow_forwardWhich of the following statements about genetically modified organisms (GMOS) are correct? Select all that apply. Question 19 options: Transgenic bacteria are used to produce protein for human consumption. Transgenic mice are frequently used to study the effects of gene mutations. Transgenic bacteria are used to produce human growth hormone. Transgenic goats have been engineered with a human gene that produces blood anticoagulant protein.arrow_forward
- Why is there a debate around the world regarding Genetically modified organism (GMO)?arrow_forwardThe use of genetically modified organisms in areas of agriculture and medicine is favored by many. However, knowing that possible risks may occur as a result of their usage, organizations who are pro-people’s right deem it necessary to oppose the commercialization of these genetically engineered products. As a youth, what is your stand to this issue and how would you make your position clear?arrow_forwardIs it safe to eat genetically modified foods?arrow_forward
- In October 2002, the government of the African nation of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the United States, enough corn to feed 2.5 million Zambians for three weeks. The government rejected the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive.” Do you agree with Zambia’s decision to turn away the corn? Why or why not? In your answer, consider that at the time, Zambia was facing food shortages, and 35,000 Zambians were expected to starve to death over the next six months. How do the risks posed by GM crops compare to the risk of starvation?arrow_forwardChoose any GMO that currently exists (bacteria, plant, animal, human), even if it was not specifically mentioned in the course materials. Next, describe the genetic modification it has undergone (i.e., the gene(s) changed, added or removed), the effect of this modification, and the benefit that the GMO provides for people. Finally, explain your personal opinion on this specific example of biotechnology.arrow_forwardGenetic engineering is a process causes the production of GMOs ( Genetically Modified Organisms) due to the ideas of biologists. The presence of the products contributes the division of the society in relation to GMOs effects. TASK: You serve as a genetic engineer, if you are given a chance what GMO would you like to produce?
