Chapter 38, Problem 10TYU
Summary Introduction
To explain: The response against genetically modified food critics.
Concept introduction: Genetically modified foods have been made by scientist by introducing certain changes in the DNA or genome of crop plants by using genetic engineering. It is very different from breeding because in this instead of getting random genes, scientists put a desired gene directly into the plant’s DNA.

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?
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.

- 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.

Crossing different strains of plants and animals followed by generations of artificial selection have yielded some successes, including the development of high-protein maize. The use of gene transfer biotechnology has led to other advances, including the creation of nutritionally enhanced rice to combat vitamin A deficiency and blindness. Researchers are now turning their attention to the nutritional enhancement of animals that are used as food. Scientists are now turning their attention to using gene transfer technology to nutritionally enhance animal foods. Recently, biotechnology was used to produce a sheep with increased amounts of an omega-3 essential fatty acid that plays an important role in the development of the nervous system and, in adults, reduces the risk of coronary artery disease. Once a small number of transgenic animals have been produced, they can be bred by conventional methods to establish a source of nutritionally enhanced meat and milk. The use of biotechnology is presenting consumers with many new choices, which will become more common in the future. Increasingly, we will all have to educate ourselves about the pros and cons of such decisions. How would you explain your decision to eat nutritionally enhanced meat from animals modified by biotechnology?arrow_forwardImproving the nutritional value of food has long been one of the goals in agricultural genetics.

- 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. In an ideal world, all solutions to improving our food system would have no negative consequences. But issues in Biology involve the interaction of many different factors and changes in one factor can lead to side effects in the others. Decisions should be made by weighing the best evidence for and against a particular choice of biotechnology. Because you'll be evaluating biotechnology you will definitely want to show your understanding of changes in gene expression The examplemof biotechnology I am using is in this link https://youtu.be/VS3kcwgIwm0.

As you continue your research, keep track of your sources. Ask yourself, should the biotechnology be used to help…arrow_forwardThe genetic modification of plants for food is a hot-button issue around the world. Genes transplanted to corn, potato, soybean, and other food strains can confer desired traits, such as resistance to pests, which lessens the need for toxic pesticides. Though genetically modified foods are thought to be safe to eat, their impact on the environment may not be fully known. Do you worry about the long-term effects of genetically modified foods on your health, or the health of the environment? Do the positive impacts outweigh the negatives?arrow_forwardAlthough it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. So why do we still use X-rays in medicine anyway? What precautions need to be taken?arrow_forward

Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?arrow_forwardGenetically modified foods are products produced from organisms that have had genetic modifications introduced into their DNA.

Additionally, biotechnology businesses create treatments or procedures (such as DNA fingerprinting). Though its use in medicine and pharmaceuticals is what makes biotechnology most well-known, the science is also used in other fields like genetics, food production, and the creation of biofuels. From this, biotechnology has its origin on where it begin. In this context, make a 600 words essay that critically review in such a way a summary that will tell and give idea on how biotechnology evolved from ancient biotechnology, classical biotechnology, and modern biotechnology.arrow_forward
