[Biodevelopers] Gen DNA sequences

[Juan Miguel Garcia Gomez]

Hello,

I'm a PhD student at Valencia, Spain. I'm working in pattern recognition
techniques applied to bioinformatic.

I'm searching at SRS and NCBI pairs of genes sequences and their
 protein trancripted associated sequences.

The problem is that I get the mRNA sequences or sequences of a full
chromosome but not a piece of DNA sequeces with the protein associated,
with introns and other subsequences.

Do you know how to get it or a database with this kind of information?

Best regards,
Juan Miguel Garcia
