Caenorhabditis elegans This worm is a well-studied model organism for developmental biology, systems biology, and genetics Lineage: Eukaryota[15557]; Metazoa[7782]; Ecdysozoa[3517]; Nematoda[201]; Chromadorea[181]; Rhabditida[177]; Rhabditina[77]; Rhabditomorpha[63]; Rhabditoidea[39]; Rhabditidae[39]; Peloderinae[26]; Caenorhabditis[25]; Caenorhabditis elegans[1]

Caenorhabditis elegans, a free-living soil nematode, is widely used as a model organism. It is transparent, and consists of 959 somatic cells. This easily cultured worm provides a model for complex organ systems, as well as developmental biology and genetics. Caenorhabditis elegans was the first multicellular eukaryotic genome to be completely More...sequenced.The Caenorhabditis elegans nuclear genome is approximately 100 Mb, distributed among six chromosomes.
