[Bioperl-l] fetch dna seqs from genbank protein ids

[Albert Vilella]

Hi bioperlers,

Got a question here:

I had a look at the fetch example scripts, and I could fetch proteins
from Genbank,
but I don't see a clear connection between the protein sequence and
the DNA sequence.
Is this a DBlink? Which type?

Cheers,

    Albert.
