<h3>Gel electrophoresis and DNA fragments</h3>

Gel electrophoresis is a method to separate DNA fragments (or RNA and other macromolecules) based on their size and charge, involving a gel called agarose. The molecules will travel through the gel at different speeds or in different directions, which allows them to be separated from each other.

Because all DNA molecules have the same amount of charge per mass, gel electrophoresis of DNA fragments separates DNA molecules based on size only. Shorter pieces of DNA travel through the pores of the gel more quickly than longer ones do.
