Database Searching of DNA (Nucleotide Sequences)

• The large databases: Genbank (US), Embl (Europe), DDBJ (Japan). These databases are quite similar regarding their contents and are updating one another periodically.
• Genomic databases: Human (GDB), mouse (MGB), yeast (SGB), etc...
• Special databases: ESTs (expressed sequence tags), STSs (sequence-tagged sites), EPD (eukaryotic promotor database), REPBASE (repetitive sequence database) and many others.
