Biochemistry & Structure of Living Cells. Select one of the following discussion topics for your primary post, which should address the discussion question in your own words. Your primary post should be at least 125 words. Also, please respond to a fellow student on any topic.
Discussion Topic 1: Internet Research on Carl Woese. Carl Woese (1928-2012) was an American scientist who was mainly interested in microorganisms – organisms so small that they can only be seen with a microscope. In particular, Woese sought to organize the known species of microorganisms, according to their relatedness, into a classification scheme. When he started, he felt that the classification schemes in use at the time were based on highly questionable assumptions, and quite possibly were complete rubbish. Therefore, he worked out a new method for classifying organisms. Research his activities on the internet, and then address issues (a), (b) and (c), that are given below, and cite your source(s).
Discussion Topic 2: Chemicals of Life Video. Watch Dr. Cox's video on the "Chemicals of Life" in the "Instructor Insights" area of Week 2. Then, address issues (a) and (b).
Discussion Topic 3: Lokiarchaeum Article. Read at least one of the two articles about Lokiarcheum (Yong, 2015; Zimmer, 2015). Both articles describe recently discovered evidence about a previously unknown organism. Address issues (a), (b) and (c), that are given below, and cite your source(s)
