Textbook Question
Chapter 14.8, Problem 1CT
Genetic engineering is used both in food crops and in medicine. Golden Rice and almost all the corn and soybeans grown in the United States contain genes from other species. The hepatitis B vaccine is produced by inserting a gene from the hepatitis virus into yeast. The antibodies in ZMapp, currently in clinical trials as an Ebola therapy, are part mouse and part human. Are there scientifically important differences in the use of genetic engineering for food or for medical purposes? Would you accept GMO products for medicine but not food? Defend your position.

AquAdvantage 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.
Genetically modified foods are products produced from organisms that have had changes
introduced into their DNA using the methods of genetic engineering. Golden rice, Flavr Savr
tomatoes and Roundup Ready soyabeans are products of this technology. Discuss the
advantages of these three genetically modified crops. Name ONE (1) strategy to produce
transformed plant cells.
A number of advances have been made in biotechnology. CRISPR/Cas9 one of the most controversial, and has had a lot of media attention in recent years. It is a method by which scientists can precisely edit DNA sequences at exact locations. Benefits obviously include the potential to “repair” mutated genes that cause disease. In fact, preliminary results from one of the earliest clinical trials of CRISPR/Cas9 provide evidence that the technique is safe and feasible to use for treating human diseases. What other potential applications of this application do you see (you can use any organisms to illustrate your answer)? What are the potential dangers or downsides of using this technology? Do you think this technology should be used in gene editing in humans? Explain your stance.

- this is an example of biotechnology: In order to increase the yield of oil from canola, research focused on ways to reduce competition from competitor weed plants. Weeds can be controlled by spraying with a herbicide that interferes with biological processes, like amino acid anabolic reactions, in the plant cells. A mutant of canola that is resistant to herbicides is sometimes grown in fields that are sprayed with the herbicide. The majority of canola in Canada, though, is genetically modified to be resistant to herbicides. also use the link: https://youtu.be/VS3kcwgIwm0 Question: Evaluating Biotechnologies in Food Systems As we practice being able to describe choices in Biology you will use this consolidation task to organize details about the advantages and disadvantages of biotechnologies.

How will you check that the correct piece of DNA is in your vector? How will you check to make sure the gene is transcribed? How will you check to make sure that the GasP protein is made in E. coli? Your investors are concerned that the GasP protein might not be sufficiently produced under normal laboratory conditions. They suggest controlling the transcription of the gasP gene using a chemical that will “trigger” its transcription. What type of promoter could be used? What chemical will you use to control transcription? How does this method of control work?arrow_forward

For instance, the gene for human insulin was isolated and moved into a bacterium, which can now produce the much-needed chemical. Previously, type 1 diabetics had to rely on professionals that gathered insulin from human cadavers, cows, and pigs. In order for this feat of genetic engineering to occur, researchers had to start with an unspliced mRNA transcript for h insulin. Agree/Disagree?

- 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…arrow_forwardBacterial transformation and bacteriophage labeling experiments proved that DNA was the hereditary material in bacteria and in DNA-containing viruses. Some viruses do not contain DNA but have RNA inside the phage particle. An example is the tobacco mosaic virus (TMV) that infects tobacco plants, causing lesions in the leaves. Two different variants of TMV exist that have different forms of a particular protein in the virus particle that can be distinguished. It is possible to reconstitute TMV in vitro (in the test tube) by mixing purified proteins and RNA. The reconstituted virus can then be used to infect the host plant cells and produce a new generation of viruses. Design an experiment to show that RNA, rather than protein, acts as the hereditary material in TMV.arrow_forwardGenetic Engineering Genetic engineering has been used in many different ways, such as human growth hormone for the treatment of pituitary dwarfism (recombinant DNA) plants engineered to be resistant to herbicides and pests an “antifreeze” gene inserted into some Atlantic salmon and halibut Select one of the examples of genetic engineering listed above and provide a description of the technology in terms of how it works and what steps are taken.
