For those studying genomics or proteomics, using the right biological databases in bioinformatics is crucial. LLRI’s article highlights essential databases: GenBank for DNA/RNA, UniProt for proteins, PDB for structures, and KEGG for pathways. It explains search functions, data formats (FASTA, GenBank), and tools like BLAST and Ensembl. The post also shares strategies for integrating multi-source data to annotate genes or model protein interactions. Whether you're involved in drug design, functional genomics, or evolutionary studies, this blog helps you navigate and utilize biological data efficiently.
