[bionet.molbio.genbank] How is the sequence data stored.

I have been reading the mail traffic lately and there seems to be lots of
interest now in new sequence data bases. I was just curious as to how the
actual sequence data is stored in the various formats, e.g. GenBank, EMBL..

What kind of compression of data exists, do they use the full 8 bits to code the
4 nucleotides or they use just two bits ?
