A genome browser is a web-based tool that allows researchers to visualize and explore the genetic information of various organisms. It provides a graphical interface to access genomic data, including gene locations, sequences, and annotations. Users can zoom in on specific regions of the genome and compare different species or strains. These tools often integrate data from various sources, such as GenBank and Ensembl, making it easier to study genetic variations and their implications. Genome browsers are essential for fields like genomics, bioinformatics, and personalized medicine, helping scientists understand the structure and function of genes.
