This no-frills UC-Santa Cruz Genome Bioinformatics Web site contains searchable "working drafts of the human genome and the mouse genome," which each represent "immense collaborative efforts" within the biomedical research community. Those who are active in genome research may find this Web site useful, especially for the multi-faceted genome browser that "provides a rapid and reliable display of any requested portion of genomes at any scale, together with dozens of aligned annotation tracks (known genes, predicted genes, ESTs, mRNAs, CpG islands, assembly gaps and coverage, chromosomal bands, mouse homologies, and more)." Users may also access Blat alignments, a table browser (provides tabular representation of the data as an alternative to the graphical display of the genome browser), downloadable versions of the data set, and more. The site also contains a helpful FAQ page and a News section that alerts the user to corrected errors, new features, etc. The extensive list of links leads to dozens of other genome databases, browsers, and related tools.
