You could do a BLAST search (blastn) vs the 'nr' (non-redundant)
nucleotide database at NCBI.  

The URL is:


There you will see a "BLAST" button which will take you to that page.

You will also find lots of documentation there as well.

If you have others questions about that page, or about 'blast' you can
direct them to:

blast-help at ncbi.nlm.nih.gov

All the best,
