Which of the following do Archaea and Bacteria have in common? They both use a special form of RNA polymerase to transcribe their DNA. They both are commonly found on human skin. They both make chitin in order to reinforce their cell membranes. They both keep their DNA in the form of a nucleoid.
There is one kingdom for eubacteria and they are all prokaryotes. They range in size from .1-15 micrometers. They have no internal components and a cell wall. Archaea is a kingdom too. They are closer to eukaryotes than bacteria are and have a cell wall and membrane. Their ribosomal proteins are similar to that of eukaryotes, and very different than bacteria. There are many different types of these, such as extremeophiles, which can live in hot or cold circumstances, and nonextreme archaebacteria which only grow in the same conditions as bacteria.
