What are characteristics of archaebacteria?


Quick Answer

Organisms classified as archaebacteria have cell walls, contain fatty acids, have complex RNA polymerase and have systems of metabolism. These features distinguish archaebacteria from other organisms. Some traits, however, are shared with organisms in other kingdoms, including Eukaryotes and Bacteria.

Full Answer

All archaebacteria have cell walls, but the structure of walls varies depending on the species. Archaebacteria lack peptidoglycan, which distinguishes them from closely related organisms in the kingdom Bacteria. Archaebacteria have membrane lipids comprised of fatty acids and have complex RNA polymerase to transcribe and copy DNA templates into RNA products. Archae also digest using a system of internal metabolism, which takes place in several stages.
