Domain Archaea - Prokaryotic, single-celled organisms; have cell walls; reproduce using binary fission (duplication); RNA sequence is most similar to Eukarya; live in extreme environments and therefore do not infect humans; oldest life forms; include methanogens, extreme thermophiles, and extreme halophiles. Domain Bacteria - Prokaryotic, single-celled organisms; have cell walls; reproduce using binary fission; differ from archaea in environment and materials in cell wall; includes cyanobac...
