Organization of The VBRC Database
The VBRC database stores viral bioinformatic data on three levels:
- Whole genomes. This level contains information about the virus species or isolate and its entire genomic sequence.
- Annotated genes. This level contains all the predicted ORFs (open reading frames) in a particular virus genome, together with their DNA and (translated) protein sequences.
- Ortholog groups (families). This level is a distinguishing feature of the VBRC database. Each annotated gene, after it has been entered into the database, is subjected to BLASTP searching against all other genes already in the database. Based on the search results, it is either assigned to a pre-existing ortholog group or placed in a newly created ortholog group of its own. The goal of this level is to "allow for quick comparison of similar genes across a given virus family."

Famous quotes containing the words organization of and/or organization:
“Science, unguided by a higher abstract principle, freely hands over its secrets to a vastly developed and commercially inspired technology, and the latter, even less restrained by a supreme culture saving principle, with the means of science creates all the instruments of power demanded from it by the organization of Might.”
—Johan Huizinga (1872–1945)
“The organization controlling the material equipment of our everyday life is such that what in itself would enable us to construct it richly plunges us instead into a poverty of abundance, making alienation all the more intolerable as each convenience promises liberation and turns out to be only one more burden. We are condemned to slavery to the means of liberation.”
—Raoul Vaneigem (b. 1934)
