Chapter 38, Problem 38.3CR
Summary Introduction
To review: How genetic engineering has improved the quality of food.
Introduction: Genetic engineering allows the direct transfer of gene of interest, between the closely or distantly related organisms. This technique involves the use of laboratory tool to cut, alter and insert the pieces of DNA that contain the gene of interest. Genetically modified crops can contain a gene that has been artificially inserted into the plant genome instead of pollination. The resulting crop is said to be “genetically modified” from their wild (original) state.

Briefly discuss the following concerns of Biotechnology;(i) Monoclonal antibodies technology versus gene technology for cancer treatment.(ii) Traditional plant breeding versus Gene technology: Which is the more efficient way for pesticide resistant crop production?(iii) Chemical technology versus Enzyme technology in industrial application.(iv) Are genetically modified organisms (GMOs) a threat to the environment?
Food plants or crops, which have been genetically altered, are known as genetically modified foods. The genetic alteration is meant to make it commercially competitive, yet it is not without environmental and ethical concerns and dilemmas. What according to you are the Four main short term benefits to the producer/consumer of genetically modified food crop, elaborate? Also identify and explain any Four long term negative impact of genetically modified food crop on the environment as well as human health.
List five genetically modified organisms (either plant or animal) in agriculture and identify the traits modified or engineered for each of them.

- What modern-day problem can be solved by Genetic Engineering? Explain the unique characteristics will be exhibited by the GMO that will solve the problem. Briefly describe each.arrow_forwardMuch of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced. Choose a side in this issue and justify your stand.arrow_forwardExamples of GMOs Correctly classify examples of bacteria, plants, and animals that have been genetically modified. Produce biofuels and other chemicals for use in manufacturing Genetically Modified Bacteria Reduce the impact of pest species by either deterring them or killing them Modified to have increased nutritional value by reducing their susceptibility to disease, increasing their rate of growth, and improving the quality of the meat/milk Provide organs for humans for transplantation Serve as models for studying human diseases such as cystic fibrosis Produce enzymes to enhance metabolic pathways to aid in the breakdown of toxic chemicals in the environment Allow organisms to better face environmental challenges such as drought, heat, and high salt content in the water supplies Reduce the number of pest species that are vectors for diseases such as Zika and dengue fever Modified to produce antibodies, vaccines, and enzymes that can be used in the treatment of humans Provide plant's…arrow_forward
- Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forwardA majority of genetically engineered crops in production worldwide today have been engineered with a gene that: A) codes for a protein that improves the nutrient value of the food B) codes for a protein which makes the crop resistant to the herbicide Roundup C) codes for a protein that allows the plant to thrive in a high-salt environment D) codes for a protein that suppresses the production of allergens in the foodarrow_forwardIn 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_forward
- (1B) Think of and identify a modern-day problem that can be solved by Genetic Engineering. If you were a scientist, what unique characteristics (at least 3) will be exhibited by the GMO that will solve the problem? Briefly describe eacharrow_forwardGenetically 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…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_forward
- Think and identify a modern-day problem that can be solved by genetic engineering. If you were ascientist, what unique characteristics (name three) will the GMO exhibit that will solve the problem?Briefly describe eacharrow_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_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_forward
