SCIN 130 AMU week 5 forum Genetics and Bioethics American Military University assistance is available on Domyclass
Please make sure to respond to the post with your original content as early in the week as possible to allow others to read and digest your material, but it is due by Wednesday at 11:55 pm EST. Make sure to give your original post a descriptive title so we all will quickly know your topic. Continue to follow your classmates’ posts for the remainder of the week and post at least 2 follow-up messages to your classmates’ posts. Pay attention to who communicates with you and respond back over the week’s discussion (create conversation!). Your follow up posts can add additional insight to your classmates’ opinions or can challenge their opinions – just make sure to do it respectfully.
Initial posts are due: Wednesday at 11:55 pm EST
Responses are due: Sunday at 11:55 pm EST, but the earlier the better
VERY IMPORTANT: Make sure to check out the grading rubric here.
Gene editing and manipulation is a newer, but rapidly growing field. We have the ability to change, add or delete genes in human embryos, adults and plants alike. We are going to explore both of these topics for this forum. You are to CHOOSE ONE of the ideas below and follow the direction.
Understand the methods and impacts of gene editing on humans and plants
Choice 1: Editing Human Embryos and Adults
With respect to gene editing in human embryos, most research is focused on fixing or removing harmful mutations that may cause diseases, but there are some fears of creating designer babies. In addition, we can edit the genes in adults, if we use a targeted approach. Read the articles below, and then respond to the prompt.
Pro and Con: Should Gene Editing be Performed on Human Embryos? Pro by Harris (2016) and Con by Darnovsky (2016).
A human has been injected with gene-editing tools to cure his disabling disease. Here’s what you need to know. (Kaiser, 2017) http://www.sciencemag.org/news/2017/11/human-has-been-injected-gene-editing-tools-cure-his-disabling-disease-here-s-what-you
CRISPR fixes disease gene in viable human embryos (Ledford, 2017)
For your original post:
- Find a reputable resource, making sure to add an attribute or URL so that we can all view it, concerning gene editing in human embryos or adults.
- Make sure to add a descriptive title so that others know what you are discussing.
- Briefly summarize the main take home points of the research – make sure to include scientific terminology and discussion (remember, we are in a biology class!).
- Some questions to consider: What is your take on the research? Are there any benefits and/or costs? Should we be focusing on this? Is there reason for concern?
Choice 2: Genetic Engineering of Plants
Genetically engineered crops are another controversial topic. They first began as a way to allow those in third world countries to grow crops that could survive in less than ideal conditions (such as drought tolerance, higher yield), and/or were higher in nutrition, meaning there was more benefit to each bite – dubbed the “Green Revolution.” You can read about it from Pingali (2012).
If you would like a little more background on genetic engineering in plants, read these resources:
Genetic engineering and GM crops (ISAAA, 2016)
Safety of genetically engineered foods (NRC, 2004)
Genetically modified plants and human health (Key, Ma & Drake, 2008)
For your original post:
- You are to find a resource, making sure to add an attribute or URL so that we can all view it, on genetic engineering of plants. You can choose a specific plant, or discuss the generic practice of modification – but it must be different than anyone else in the class or you will not receive credit.
- Make sure the title of your post is descriptive so that others know what you are discussing.
- Briefly summarize the main take home points of the research – make sure you use proper scientific terminology and discussion (remember we are in a biology class).
- Some questions to consider: Is it ethically responsible to engineer plants? Does it make a difference whether they are geared towards first or third world countries? Will they help or hinder our efforts to feed the ever-growing world population?
