Gene search

Definition

Gene search refers to the process of identifying and locating specific genes within a genome, which is crucial for understanding their functions, interactions, and roles in various biological processes. This process often utilizes genome browsers, which provide a graphical interface for visualizing genomic data, making it easier to find genes of interest along with associated annotations like variations, expression patterns, and regulatory elements.
