The Mar. 2007 Petromyzon marinus draft assembly (WUSTL v.3.0 (March 2007)) was produced by the Genome Sequencing Center at Washington University School of Medicine in St. Louis (WUSTL).
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 Lamprey genome. See the User's Guide for more information.

The genome has been sequenced to 5.9X coverage. Please note the
description of the assembly in the WUSTL
The UCSC browser displays the 108,241 contigs, containing 831,696,438 bases of sequence, and 195,562,529 bases in gaps (N's in the sequence) between fragments of the contigs. The largest contig, Contig0 is 273,059 bases, and one half of the sequence is contained in 21,088 contigs of size 14,239 (N50) bases are larger.
The mitochondrial genome sequence has been included as chrM. This is sequence from the genbank record NC_001626 accession 5835065.
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 Lamprey browser 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 the success of this release.
