This animation shows the steps for running an electrophoresis gel and explains how this gel works to separate DNA fragments.

Agarose gel electrophoresis is a technique for separating DNA of different lengths or sizes. Learn how to make an agarose gel, load DNA samples, separate them by electrophoresis and estimate size by comparison to a ‘DNA ladder’ in this short animation.
