Retrieving a sequence from a remote database with Bio∷DB∷EMBL. This code retrieves an mRNA sequence in EMBL format from the EBI EMBL databank with the accession no. U14680 and writes the sequence out in GenBank format to the terminal. One could replace Bio∷DB∷EMBL with Bio∷DB∷GenBank and instead retrieve the sequence from NCBI just as easily, as the software can read and write both EMBL and GenBank formats and is able to connect to both services through the World Wide Web. The retrieved sequence can then be passed to Bio∷Graphics for graphical rendering, to the Bio∷SeqIO interface for writing to a file, or to the ODBA interfaces for storage in a relational database.
