| Name | Description |
| All DNA Databases | Includes all entries in GenBank and the abridged EMBL (GenEMBLPlus). |
| DNA Databases excluding GSS, EST, and STS | Includes sequences from all divisions of both DNA databases except the GSS, EST, and STS divisions (GenEMBL). |
| EST, GSS, and STS | Includes only sequences from the EST, STS, and GSS divisions of GenEMBLPlus (Tags). |
| Expressed Sequence Tags (EST) | Includes sequences derived from sampling cDNA libraries. Entries are mostly short and generated by automatic sequencing. |
| Genome Survey Sequences (GSS) | Includes short sequences from several genomes. Most entries have been generated by automatic sequencing. |
| Sequence Tagged Sites (STS) | Includes short, randomly primed regions of several genomes. The location of the entries make them important markers for genome mapping and sequencing. |
| Bacterial | Includes sequences derived from bacteria species. |
| High Throughput Genomes (HTG) | Include long, contiguous regions of several genomes usually at the cosmid level or longer. The entries are considered finished sequences. |
| Invertebrate | Includes sequences derived from invertebrate species. |
| Organelle | Includes sequences from mitochondria and other organelles. (EMBL only; GenBank entries are in the division of the host species). |
| Mammalian without Primate and Rodent |
Includes sequences from all mammalian species except primates and rodents. |
| Vertebrate without Mammalian | Includes sequences from all vertebrate species except mammalian species. |
| Patent | Includes sequences submitted to the public databases by the European and United States Patent Offices. |
| Phage | Includes sequences from bacteriophage. |
| Plant | Includes sequences from plant, fungal, and algal species. |
| Primate | Includes sequences from primate species. |
| Rodent | Includes sequences from rodent species. |
| Structural RNA | Includes RNA sequences with solved structures. (Not all structural RNAs have a solved structure.) |
| Synthetic | Includes man-made sequences, mostly vectors, regions of vectors, or genetically engineered plasmids. |
| Unannotated | Includes entries which have incomplete documentation or other problems. Entries in this division will move to another division in a future database release. |
| Viral | Includes sequences from all viral species except bacteriaphage. |
| Name | Description |
| SWISS-PROT | Includes all SWISS-PROT entries. |
| Translated EMBL | Includes most of the proposed translated regions of the complete EMBL except those regions with entries already in the SWISS-PROT database (SP-TREMBL). |
| SWISS-PROT plus Translated EMBL | Includes all SWISS-PROT and SP-TREMBL entries (SwissProtPlus). |
| PIR-Protein | Includes all PIR entries. |
