A genome browser is a web-based tool that allows researchers to visualize and explore the genetic information of various organisms. These platforms display the structure of genomes, including genes, regulatory elements, and other important features, making it easier to analyze genetic data. Users can navigate through different regions of the genome, compare sequences, and access annotations that provide insights into gene functions and variations. Popular genome browsers include UCSC Genome Browser, Ensembl, and NCBI Genome Data Viewer, each offering unique features and datasets for a wide range of species.
