  About the Helix Systems Mirror Fragments

This site contains the reference sequence for a handful of genomes from the UCSC Genome Browser: human, rhesus monkey, mouse, rat, guinea pig, dog, cow, chicken, Drosophila, and zebrafish genomes.

We encourage you to explore these sequences with our tools. The Genome Browser zooms and scrolls over chromosomes, showing the work of annotators worldwide. The Gene Sorter shows expression, homology and other information on groups of genes that can be related in many ways. Blat quickly maps your sequence to the genome. The Table Browser provides convenient access to the underlying database. Genome Graphs allows you to upload and display genome-wide data sets.

The UCSC Genome Browser is developed and maintained by the Genome Bioinformatics Group, a cross-departmental team within the Center for Biomolecular Science and Engineering (CBSE) at the University of California Santa Cruz (UCSC). If you have feedback or questions concerning the tools or data on this website, feel free to contact us on our public mailing list. To view the results of the Genome Browser users' survey we conducted in May 2007, click here.

10 August 2009 - Updated Yeast Genome Browser Released
We have added the June 2008 release of the yeast genome (Saccharomyces cerevisiae) based on sequence from the Saccharomyces Genome Database (SGD). The sequence, open reading frame (ORF), and gene annotations were downloaded from the site ftp://genome-ftp.stanford.edu/pub/yeast/data_download.

The S288C strain was used in this sequencing project. Reference information for each chromosome may be found in the SGD Systematic Sequencing Table. Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page.

See the Credits page for details on contributions to this release.


22 July 2009 - Updated Opossum Genome Browser Released
We have released an updated opossum (Monodelphis domestica) genome browser, UCSC version monDom5, corresponding to the Broad Institute's October 2006 assembly. Read more.


7 July 2009 - Engineering Job Opening with UCSC Genome Browser Project The UCSC Center for Biomolecular Science and Engineering is currently accepting applications for a full-time, experienced engineer Read more.


  Conditions of Use

The sequence and annotation data displayed in the Genome Browser are freely available for any use with the following conditions:

  • Genome sequence data use restrictions are noted within the species sections on the Credits page.
  • Some annotation tracks contributed by external collaborators contain proprietary data that have specific use restrictions. To check for restrictions associated with a particular genome assembly, review the database/README.txt file in the assembly's downloads directory.

The Genome Browser and Blat software are free for academic, nonprofit, and personal use. A license is required for commercial use. See the Licenses page for more information.

Program-driven use of this software is limited to a maximum of one hit every 15 seconds and no more than 5,000 hits per day.

For assistance with questions or problems regarding the UCSC Genome Browser software, database, genome assemblies, or release cycles, see the FAQ.
