The August 2006 Bos Taurus draft assembly (Baylor release Btau_3.1) was produced by the Baylor College of Medicine Human Genome Sequencing Center.

### Sample position queries

A genome position can be specified by the accession number of a sequenced genomic region, an mRNA or EST, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the cow genome. See the User's Guide for more information.

Request: |  | Genome Browser Response:
--- | --- | ---
chr28 |  | Displays all of chromosome 28
chr28:1-1000000 |  | Displays first million bases of chromosome 28
chr28:1000000+2000 |  | Displays a region of chr 28 that spans 2000 bases, starting with position 1000000
BC140604 |  | Displays region of mRNA with GenBank accession number BC140604
DY058268 |  | Displays region of EST with GenBank accession DY058268 on chr X
pseudogene mRNA |  | Lists transcribed pseudogenes, but not cDNAs
homeobox caudal |  | Lists mRNAs for caudal homeobox genes
zinc finger |  | Lists many zinc finger mRNAs
kruppel zinc finger |  | Lists only kruppel-like zinc fingers
zhang |  | Lists mRNAs deposited by scientist named Zhang
Moore,S. |  | Lists mRNAs deposited by co-author S. Moore
Use this last format for author queries. Although GenBank requires the search format Moore S, internally it uses the format Moore,S..

### Assembly details

The Btau_3.1 release was produced by the Atlas genome assembly system at Baylor College of Medicine Human Genome Sequencing Center. The sequencing strategy combined BAC shotgun reads with whole genome shotgun reads from small insert libraries as well as BAC end sequences. The assembly contains chromosomes 1-29 and X as well as 13045 scaffolds (named chrUn.003.*). For detailed information on the sequencing and assembly techniques, see the Readme file that accompanies this release and the Baylor Bovine Genome Project web page.

Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page. These data have specific conditions for use. The bosTau3 annotation tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to this release.
