Question: Which of the following is considered the first biological database?
A GenBank
B Protein Data Bank (PDB)
C Swiss-Prot
D NCBI Entrez
Answer: Protein Data Bank (PDB)
| Database | Organization | Description |
| Protein Data Bank (PDB) | Worldwide Protein Data Bank (wwPDB) consortium (1971) | · A database that stores 3D structural data of biological macromolecules. · It primarily focuses on proteins and some nucleic acids. · It provides valuable insights into the three-dimensional structures of biomolecules. |
| GenBank | National Center for Biotechnology Information (NCBI) (1982) | · It primarily stores DNA sequences, including genomic DNA, genes and other genetic information. |
| Swiss-Prot | Swiss Institute of Bioinformatics (SIB) as part of the UniProt consortium (1986) | · A database of protein sequences and their functional information, curated with a high level of annotation and accuracy. · It is part of the UniProt consortium and is known for its reliability in protein information. |
| NCBI Entrez | National Center for Biotechnology Information (NCBI) (1991) | · It encompasses various databases, including GenBank and provides access to a wide range of biological and biomedical data such as DNA and protein sequences. |
