The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several
