Genome browser

Definition

A genome browser is a web-based tool that allows researchers to visualize and explore genomic data in an interactive manner. By providing graphical representations of genomic features such as genes, regulatory elements, and variations, genome browsers facilitate the analysis and interpretation of complex biological information. They are essential in proteomics and genomics approaches, as they help researchers correlate genetic data with phenotypic traits and understand gene function.
