Gel [[electrophoresis]] is a technique used to separate [[DNA]], [[RNA]], or proteins based on their size and charge. It involves running molecules through a [[gel]] [[matrix]] under the influence of an [[electric field]], resulting in the separation of molecules into distinct bands that can be visualized.
