Go to the "Gene" data base. Type “ferrochelatase” into the search box and click on the “Go” button. Under the “Genomic regions, transcripts and products” section find the link to “NC000018” and click on it, then select “GenBank”. Make sure that the accession number at the top of the GenBank record matches the accession number given in the "Gene" database record.
