Gel electrophoresis

Gel electrophoresis is a laboratory technique used to separate and analyze molecules, often DNA, RNA, or proteins. It involves placing a sample in a gel, which acts like a sieve, and applying an electric current. As the current flows, molecules move through the gel at different speeds based on their size and charge; smaller molecules move faster than larger ones. This separation allows scientists to visualize and study these molecules, helping in various fields like genetics, forensics, and biochemistry to understand biological processes or identify genetic material.
