Bis 2C, Pre-Lab #2 Bacteria and Archaea are often collectively referred to as prokaryotes because they lack a nucleus (pro=before, karyon=nucleus). But, as you can see from figure 2.1, they are not each other’s closest relatives. Because bacteria and archaea are so diverse, they can be difficult to characterize. However, when compared to eukaryotes, they have significant differences in their general biology including, reproduction, organization of genetic material, and a lack of membrane...
