What is a characteristics of archaebacteria?

Answer 1

When first discovered in 1977 archaebacteria were classified as bacteria. They are now called Archaea. This change is to emphasise the difference between archaea and bacteria. Archaea are one of the three domains of life suggested by Carl Woese. The other two are Prokaryotae (bacteria) and Eukaryotae (everything else - plants, animals, fungi and protoctists). The features which distinguish archaea from other organisms include: 1) They have prokaryote cells (which have significant differences from other prokaryotes ie the bacteria) 2) The have lipids in their cell membranes composed of branched hydrocarbon chains attached to glycerol by ether linkages, instead of ester linkages 3) Their cell walls do not contain peptidoglycan, as bacterial cell walls do 4) They differ from bacteria in their sensitivity to antibiotics 5) They contain ribosomal RNA (rRNA) which differes from that found in bacteria and eukaryotes.
