However, prokaryotes differ from eukaryotic cells in several ways. 61, 127148 (1991). The Bacteria and Archaea have been grouped together and called Prokaryotes because of their lack of a nucleus, but the Archaea are more closely related to the Eukaryotes than to the Bacteria. Open Access articles citing this article. Biol. Although we have seemingly answered some of these questions, others remain fiercely debated, and new questions continue to arise. These include fimbriae, short protrusions found all over the surface of the bacterium; a flagellum, found at the back of the bacterium and used for propulsion; and a sex pilus, used to grab on to other bacteria for exchange of genetic material. This study, based on analyses of ribosome structures, proposes that eukaryotes might have evolved from within the archaeal domain of life. J.L. & Archibald, J. M. More protist genomes needed.

Article Methane metabolism in the archaeal phylum Bathyarchaeota revealed by genome-centric metagenomics.

The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration. 29, 32613265 (2012). This paper proposes a thorough systematic analysis of the phylogenetic relationships between ancestral eukaryotic genes and archaeal and bacterial genes. Eukaryotic cells are much larger and more complex than prokaryotes and contain several cell structures and organelles that are missing from prokaryotic cells. This paper describes the discovery of Lokiarchaeota and provides evidence that they form a monophyletic group with eukaryotes and that their genomes encode an expanded repertoire of ESPs.
