Gel electrophoresis is a technique used to separate DNA fragments according to their size.
DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel.
DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
When a gel is stained with a DNA-binding dye, the DNA fragments can be seen as bands, each representing a group of same-sized DNA fragments.
