### 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 Elephant genome. See the User's Guide for more information.

Request: |  | Genome Browser Response:
--- | --- | ---
scaffold_17 |  | Displays all of scaffold 17
scaffold_17:1-1000000 |  | Displays first million bases of scaffold 17
scaffold_17:1000000+2000 |  | Displays a region of scaffold 17 that spans 2000 bases, starting with position 1000000
BX950328 |  | Displays region of mRNA with GenBank accession number BX950328

homeobox caudal |  | Lists mRNAs for caudal homeobox genes
zinc finger |  | Lists many zinc finger mRNAs
kruppel zinc finger |  | Lists only kruppel-like zinc fingers
janke |  | Lists mRNAs deposited by scientist named Janke
Taguchi,T. |  | Lists mRNAs deposited by co-author T. Taguchi
Use this last format for author queries. Although GenBank requires the search format Taguchi T, internally it uses the format Taguchi,T..

### Assembly details

The genome has been sequenced to 7X coverage. There are 2,352 scaffolds with a total size of 3,196,743,967 bases, and the mitochondrial genome chrM (genbank accession NC_000934, size 16,866 bases).
The N50 size of the scaffolds is 46,401,353 bases with 21 scaffolds larger, and 2,331 scaffolds smaller. The mean scaffold size is 1,359,159 bases, the median scaffold size is 10,119.
