genomic DNA databases

[Michael Thompson]

					Does anyone know of any WWW sites which allow searches of any of 
the genomic DNA databases?  The only ones I have seen so far allow 
searches only by gene name or accession number, and I am looking for a 
database which I can search with a portion of a cDNA to see if the 
genomic fragment from which it originated from has been sequenced and 
submitted.
