As with other model organisms, the fully sequenced
zebrafish genome has acted as an invaluable reference tool for scientists.
Scientists at the Wellcome Trust Sanger Institute therefore set about sequencing
the zebrafish genome in February 2001.
Sequencing
the zebrafish genome provided evidence of more than 26,000 protein - coding genes, the largest set of any vertebrate sequenced so far.
The community got together to initiate the sequencing of the whole
zebrafish genome, which began in 2001 at the Wellcome Trust Sanger Institute in Cambridge.
This information would then be added into the core Ensembl gene - set (the reference
zebrafish genome used by researchers around the world) in such a way as to increase the quantity and quality of the gene - set without adding artifacts or pseudogenes.
Like the human genome,
the zebrafish genome has two copies of each gene, and scientists can remove the function of multiple genes to produce phenotypes that are reminiscent of human symptoms.
