[citation needed] They contain information from research areas including genomics, proteomics, metabolomics, microarray gene expression, and phylogenetics.
Databases are important tools in assisting scientists to analyze and explain a host of biological phenomena from the structure of biomolecules and their interaction, to the whole metabolism of organisms and to understanding the evolution of species.
Biological database design, development, and long-term management is a core area of the discipline of bioinformatics.
Each of these can be found from certain sources, for example:[citation needed] Biological knowledge is distributed among countless databases.
Other popular model organism databases include Mouse Genome Informatics for the laboratory mouse, Mus musculus, the Rat Genome Database for Rattus, ZFIN for Danio Rerio (zebrafish), PomBase[4] for the fission yeast Schizosaccharomyces pombe, FlyBase for Drosophila, WormBase for the nematodes Caenorhabditis elegans and Caenorhabditis briggsae, and Xenbase for Xenopus tropicalis and Xenopus laevis frogs.
[6] The Catalogue of Life is a collaborative project that aims to document taxonomic categorization of all currently accepted species in the world.
The Catalogue of Life curates up-to-date datasets from other sources such as Conifer Database, ICTV MSL (for viruses), and LepIndex (for butterflies and moths).
[10] Sources for this new database included books, literature, GPS tracking, and online webpage data.
An important resource for finding biological databases is a special yearly issue of the journal Nucleic Acids Research (NAR).
