This week you are exploring how emerging DNA technologies impact our society. For your primary post, respond to one of the following three topics and be sure to answer each of the questions. Also, please reply to at least one fellow student on any topic.Topic 1 [video]: Jennifer Doudna on CRISPR. View the NBC News story about CRISPR (1)*, including an interview with its co-discoverer, Jennifer Doudna. Then, address the following questions:(a) What applications of CRISPR look particularly promising for improving human well-being? (b) What sort of ethical issues have arisen or are likely to arise with the deployment of CRISPR?Topic 2 [Reading]: Societal Aspects of Human Gene Editing. Read the article by Neuhaus (2)* and/or the article by Ossola (3)*, then address the following:(a) What do you think our procedures, regulations, and laws ought to be regarding human genome editing, with CRISPR (or any other tool)? (b) Explain your rationale. Topic 3 [Reading]: Esvelt’s Regret. In the article by Zimmer (4)*, Kevin Esvelt says that he made a huge mistake by championing the application of a technology that he now says is far too dangerous to actually deploy. Based on the article, address the following:(a) What is the technology that he championed? What does it consist of and why does he think it’s too risky to use outside the lab?(b) In your opinion, what sorts of laws and regulations, if any, should society put into place to regulate the technology that Esvelt regrets championing? *References (in Strayer Writing Standards format).

The Major Components of LifeProkaryotic and eukaryotic are the two major categories of cells making up life on earth. Both these types require water and carbon.Describe the characteristics of water and carbon that makes them important to living things in general, and to specific forms of life including plants, animals, and prokaryotes. Why is NASA looking for water on Mars?Describe the differences in prokaryotic and eukaryotic cells. How have the characteristics of each kind of cell put limitations and provided opportunities for the survival and divergence of modern living things? Why might both cell types be considered equally successful? Make sure to consider both Domains of Prokaryotes.The essay must be informed by the textbook.

Describe the process of cell division (mitosis) and gamete formation (meiosis). Be sure to describe the overall role of both process as well as a detail description of all phases of both processes. Make sure that you make a direct comparison between the two processes focusing on their specific similarities and differences. Figures or diagrams can be used but CANNOT replace the written description or narrative.
