WebGenetically, archaea are closer to eukaryotes (IIRC this first showed up in the sequence of ribosomal RNAs), and they have histone proteins (which bacteria don’t) and initiate protein synthesis with methionine, whereas bacteria use N-formyl-methionine, and they have multiple RNA polymerases, while most bacteria have only one. WebThe inferred composite trees reveal that archaebacteria are more closely related to eukaryotes than to eubacteria for all the cases. By bootstrap resamplings, this relationship is reproduced with probabilities of 0.96, 0.79, 1.0, and 1.0 for elongation factors Tu and G and for ATPase subunits alpha and beta, respectively.
