Chapter 30, Problem 12TYU
SCIENCE, TECHNOLOGY, AND SOCIETY
People have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization processes that significantly modify the genomes of organisms. Why do you think modern genetic engineering, which often entails introducing or modifying only one or a few genes, has met with so much public opposition? Should some forms of genetic engineering be of greater concern than others? Explain.

Students have asked these similar questions
To create genetically modified organisms (often called GMOS) scientists directly manipulate
the genes of an organism, often by inserting or deleting one or more genes. The inserted gene is
usually from another species. The purpose of this manipulation is to give the target organism and its
offspring a new trait that improves it in some way. The improvement might, for example, give the
organism higher vitamin content. The process is called genetic engineering.
1. What are genetically modified organisms?
2. What is Genetic engineering?
Genetic engineering utilized to create food sources has been said to be both like and unlike traditional breeding. One way it is different is:
It mixes genes from different individuals of the same or similar species
It involves whole organisms living in the field
It selects from combinations of genes that come together on their own
It mixes genes of different organisms such as viruses and crops, or spiders and goats
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
pick one of the examples of genetic engineering listed above to expand on.
Provide a description of the technology in terms of how it works and what steps are taken

But there are also many bad things as well. From the article by Bio medical about the pros and cons of having a designer baby it states that a pro is that this type of engineering can “ might help prevent genetic diseases such as Alzheimer’s, Huntington’s Disease, down syndrome, Spinal Muscular Atrophy, and many others”. I think that it is great that we could get rid of Alzheimer’s due to how destructive it can be to the people that suffer it. But I think the other diseases that it can eliminate is horrible due to them making our world a more unique place such as people with autism, Down syndrome. By doing this it could eliminate the whole population of people with disabilities community and make everyone “normal”.

- Is genetic engineering a pure scientific process or it is indeed an act of humans playing like God?arrow_forwardLiving things and molecular biology are used in the science-based industry sector of biotechnology to create medical products. 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. In this context, make an essay on how biotechnology evolved from ancient biotechnology, classical biotechnology, and modern biotechnology.arrow_forwardthis 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.
