For 10 points, name this domain of extremophiles, distinct from Eukarya and Bacteria.
S ribosomal RNA was pioneered to study this taxon. Because cells in this taxon have psuedomurein rather than muramic acid, the monosaccharides form 1,3-glycosidic linkages. Phospholipids in these organisms consist of ether linkages between isoprene-based fatty acids and have the L-stereoisomer of glycerol. Carl Woese pioneered the study of this domain, which has four or five known phyla. Some organisms in this domain can metabolize carbon dioxide to methane and live in the digestive tract of cows. Members of this domain lack peptidoglycan in their cell walls. For 10 points, name this domain of extremophiles, distinct from Eukarya and Bacteria.
