Cartoon of a purple amoeba looking up at a spiraling double helix while a pink amoeba looks toward the viewer from the opposite side. Title card reads, "Gel Electrophoreses."

Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells 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. Part of "The Amoeba Sisters" series.
