Bacteria archaea and eukaryota. In 1990 that divides cellular life forms into archaea bacteria and eukaryote domains. Domains are the top level classification which categorizes life in the most general way. The three domains are the archaea the bacteria and the eukarya.
There are currently 3 agreed groups at this level the archaea domain bacteria domain and eukarya domain. Archaea prokaryotic organisms which live in. 2010 11 04 16 45 23 2010 11 04 16 45 23. A phylogenetic tree based on rrna data emphasizing the separation of bacteria archaea and eukaryotes as proposed by carl woese et al.
The domain swapping that gives rise to gene families and superfamilies are natural genetic events. Prokaryotic organisms belong either to the domain archaea or the domain bacteria. Eukaryote are further grouped into kingdom protista algae protozoans etc kingdom fungi yeast mold etc kingdom plantae flowering plants ferns etc and kingdom animalia insects vertebrates.

The three domain system is a biological classification introduced by carl woese et al. Each domain contains a collection of organisms with similar properties and evolutionary histories as scientists have organized them. Because protein domains can also be swapped by genetic engineering to make. As the name suggests the eukaryote are eukaryotic cells which have membranes that are pretty similar to that of bacteria.
Domain names often derive from their prominent biological function in the protein they belong to e g the calcium binding domain of calmodulin or from their discoverers the ph domain. For example it separates the presence of a nucleus.

The key difference from earlier classifications is the splitting of archaea from bacteria.
