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...
