By now you are getting the idea that what seems like clear lines drawn between eukaryotic cells and prokaryotic cells may be not quite as clear as you previously thought. For example, let's think about cell walls. The prokaryotes and some eukaryotes have cell walls, but they aren't made of the same material. The cell membranes of archaebacteria and eubacteria are structured differently, but they both have cell membranes, as do eukaryotes. It's this variation on a theme that people interested in life science find fascinating. The fascination grows as scientists manipulate prokaryotes and eukaryotes through the cells' genes.
In this last section, you can choose an area of interest to explore. There are three sections with one or more topics and links below it.
Insulin—This site shows the steps in the recombinant DNA process.
Eukaryotic Stem Cells—Click the "Stem Cells Home" tab to view Stem Cells 101 and two or three other movies in the series.
Bioremediation—Bacteria and other microbes are used to clean up toxic waste.
GMO—The first link describes what GMOs are and how they are used in our society. The second and third links are slide shows about how one specific bacteria is used in GMO process.
The Human Microbiome—This article explores our complex human ecosystem.
