The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
