(A) The UCSC Genome Browser organizes the display of genomic information with the official or reference genome sequence as the framework, positioning additional data as “annotation tracks” in the appropriate genomic location to provide context for understanding any genomic region. (B) An underlying mySQL database stores genomic sequence data, annotation track details, and auxiliary information which can then be visualized with the graphical Genome viewer interface, or queried and downloaded using the Table Browser interface.
