Analysis of 16s rRNA has led to the designation of a third group within it; the organisms of this  group may be ancestral to the previously known groups.
Analysis of 16s rRNA has led to the designation of a third group within it; the organisms of this  group may be ancestral to the previously known groups. They have histones, use methionine as an initiator  amino acid, and have ether-linked lipids. While they share many features on the cellular structure level  with bacteria, including a general prokaryotic makeup, analysis of rRNA sequences and subunit binding of  polymerases showed them to be more closely related on a molecular level to eukaryotes, a discovery that led  to them being accorded a domain of their own name. For ten point, identify this domain of organisms, first  classified as such by Carl Woese "WOES", whose members include extremophiles and methanogens.
