Genomic databases are organized collections of genetic information that store data about the DNA sequences of various organisms. These databases help researchers analyze genetic variations, understand diseases, and develop new treatments. Examples include the National Center for Biotechnology Information (NCBI) and the Ensembl Genome Browser. These databases often contain information on gene functions, genetic markers, and evolutionary relationships. They are essential tools for scientists in fields like genomics, bioinformatics, and personalized medicine, enabling them to share and access vast amounts of genetic data for research and clinical applications.
