Gel electrophoresis is used to separate and analyze biomolecules, such as DNA, RNA, and proteins. By applying an electric field to a gel matrix, charged molecules migrate at varying speeds based on their size and charge. This process enables researchers to visualize and quantify nucleic acids and proteins, making it an essential tool for genetic research, forensic analysis, and medical diagnostics. Its reliability, efficiency, and capacity for high-throughput analysis make it indispensable for scientists seeking to unlock the obscurities of the molecular world.
