Bioinformatics databases are organized collections of biological data that facilitate the storage, retrieval, and analysis of information related to genes, proteins, and other biological molecules. These databases often contain sequences, structures, and functional annotations, making it easier for researchers to access and compare biological information. Examples of popular bioinformatics databases include GenBank, which provides nucleotide sequence data, and UniProt, which focuses on protein sequence and functional information. These resources are essential for advancing research in fields like genomics, proteomics, and systems biology, enabling scientists to make discoveries and develop new therapies.
