	How are archaea similar to Eukaryotes?	~30% of shared genes code for proteins for transcription, translation, & DNA metabolism share molecular biology traits evidence of lateral transfer (both)
	How are archaea similar to Eubacteria?	shared genes are involved in metabolic pathways evidence of lateral transfer (both)
	Why are archaea important?	resembles earth's earliest life forms alternative energy production some consume methane original cell that accepted bacteria as organelles was an archeaon very different from other life forms; often act as a bridge and/or ancestor between bacteria and eucaryotes
	How are archaea different from bacteria and eukarya?	they have ether linkages (NOT ester) in cell membranes some have tetraether monolayer membranes may stain Gram+ and Gram- but DO NOT have normal cell walls - NO PTG instead have pseudomurein an X-linked glycan with L-amino acids
	Do archaea resemble Eukaryotes or Bacteria most?
