 It is possible for two CDS sequences from separate genes, within a species, to be identical and so it is possible to have identical proteins coded for by separate genes.When this happens, a single, unique identifying name is used for the protein even though it is produced by two genes.WormBase ParaSite is a sub-portal for approximately 100 draft genomes of parasitic helminths (nematodes and platyhelminthes) developed at the European Bioinformatics Institute and Wellcome Trust Sanger Institute.
