Genome sequence and annotation have been imported from the WS240 release of WormBase (which includes the WBcel235 version of the C.elegans reference genome). Included are annotated operons, genes, transcripts and translations, as well as RNAi and BLAST/BLAT homology data. In addition Affymetrix and Agilent cross references for C.elegans expression arrays have been added.
We include C.elegans in Ensembl (and also Ensembl Genomes) to allow people to access the data through the Ensembl user interface (both for visualisation and data mining) and to provide cross-species integration through our comparative genomics resources (such as homologous gene links and protein family pages).
The genome assembly represented here corresponds to Genome Assembly ID GCA_000002985.3

Genes and/or transcript that contains an open reading frame (ORF).
|Small non coding genes|
Small non coding genes are usually fewer than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as small non coding genes: miRNA, miscRNA, rRNA, tRNA, scRNA, snlRNA, snoRNA, snRNA, tRNA, and also the pseudogenic form of these biotypes. The majority of the small non coding genes in Ensembl are annotated automatically by our ncRNA pipeline.
|Long non coding genes|
Long non coding genes are usually greater than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as long non coding genes: 3prime_overlapping_ncrna, ambiguous_orf, antisense, antisense_RNA, lincRNA, ncrna_host, non_coding, non_stop_decay, processed_transcript, retained_intron, sense_intronic, sense_overlapping. The majority of the long non coding genes in Ensembl are annotated manually by HAVANA.
A pseudogene shares an evolutionary history with a functional protein-coding gene but it has been mutated through evolution to contain frameshift and/or stop codon(s) that disrupt the open reading frame.
|Gene transcriptsNucleotide sequence resulting from the transcription of the genomic DNA to mRNA. One gene can have different transcripts or splice variants resulting from the alternative splicing of different exons in genes.||56,820|
