The document discusses various biological databases including: 1. Nucleic acid, protein, and structure databases that store gene and protein sequence data, protein structures, and related information. 2. Specialized databases focused on specific topics like virus structures or immunology. 3. Expression and proteomics databases that record gene expression measurements.
