  5. The two microscopic organisms and archaea have diverse Ribosomal RNAs (rRNA).
  6. Archea have three RNA polymerases like eukaryotes, yet microorganisms have just one. Archaea have cell dividers that need peptidoglycan and have films that encase lipids with hydrocarbons as opposed to unsaturated fats.
