All living organisms are classified into one of three domains: Bacteria, Archaea, and Eukarya. Compare and contrast the domains Bacteria and Archaea. How are they alike? How are they different?
Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences.
