The article describes the University of California, Santa Cruz (UCSC) Human Genome Browser, a web-based tool for visualizing and analyzing the human genome. The browser provides a comprehensive display of various annotations, including gene predictions, mRNA alignments, homology with other species, single nucleotide polymorphisms (SNPs), and more. It supports interactive searches and allows users to view genome regions at different scales, from entire chromosomes to specific genes. The browser is highly integrated with the BLAST sequence search tool and uses a MySQL database to efficiently manage and retrieve data. Users can also add custom tracks for educational or research purposes. The UCSC browser has become a valuable resource for researchers, serving over 50,000 pages per day to more than 3,000 users. The article details the conceptual framework, technical implementation, and features of the browser, highlighting its speed, stability, and user-friendly interface.The article describes the University of California, Santa Cruz (UCSC) Human Genome Browser, a web-based tool for visualizing and analyzing the human genome.
