question: Which algorithm is used by the UCSC Genome Browser?
answer: The UCSC Genome Browser organizes data and annotations (called tracks) around the reference sequences or draft assemblies of many eukaryotic genomes and presents them using a powerful web-based graphical interface. The database is optimized to support fast interactive performance with the web-based UCSC Genome Browser, a tool built on top of the database for rapid visualization and querying of the data at many levels. The annotations for a given genome are displayed in the browser as a series of tracks aligned with the genomic sequence. Sequence data and annotations may also be viewed in a text-based tabular format or downloaded as tab-delimited flat files.
