The Caenorhabditis elegans genome assembly is based on sequence version WS100 deposited into WormBase as of 02 May 2003. C. elegans is a major model organism used for biomedical research. It is the first multicellular animal to have a fully sequenced genome, a joint collaboration between the Genome Sequencing Center at Washington University in St. Louis and the Sanger Institute. For more information, see the special issue of Science "C. elegans: Sequence to Biology".

The ce1 sequence and annotation data may be downloaded from the UCSC Genome Browser FTP server or Downloads web page. The ce1 annotation tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to the success of this release.

Sample position queries

A genome position can be specified by the accession number of a sequenced genomic clone, an mRNA, or EST, or a gene identifier, chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the C. elegans genome. See the User's Guide for more information.

Request:	Genome Browser Response:
chrII		Displays all of chromosome II (valid chr entries include I, II, III, IV, V, M, X)
chrI:1-100000		Displays the first 100,000 bases of chrI
U40798.1		Displays clone fragment U40798.1
mec-8		Displays region of genome associated with RefSeq gene mec-8
F46A9.4		Displays the region associated with the Sanger predicted gene F46A9.4
NM_060107		Displays region of genome associated with RefSeq identifier NM_060107
BJ111711		Displays region of EST associated with GenBank accession BJ111711
zinc finger		Lists many zinc finger mRNAs
ring zinc finger		Lists only RING zinc fingers
Jones,D.		Lists mRNAs deposited by co-author D. Jones
Use this last format for author queries. Although GenBank requires the search format Jones D, internally it uses the format Jones,D..
