Agarose gel

An agarose gel is a laboratory tool used to separate molecules like DNA or proteins based on size. It consists of a jelly-like substance derived from seaweed, poured into a tray to create a gel with tiny pores. When an electric current is applied, charged molecules move through the pores; smaller molecules travel faster and farther, while larger ones move more slowly. This process helps scientists analyze, identify, or purify specific molecules. Agarose gel electrophoresis is a common technique that provides a visual way to study genetic material or proteins.
