title: Archaebacterial genomes: eubacterial form and eukaryotic content.
abstract: Since the recognition of the uniqueness and coherence of the archaebacteria (sometimes called Archaea), our perception of their role in early evolution has been modified repeatedly. The deluge of sequence data and rapidly improving molecular systematic methods have combined with a better understanding of archaebacterial molecular biology to describe a group that in some ways appears to be very similar to the eubacteria, though in others is more like the eukaryotes. The structure and contents of archaebacterial genomes are examined here, with an eye to their meaning in terms of the evolution of cell structure and function.
