Learning Objective

I can describe the principles of gel electrophoresis.

  • 1

    Gel electrophoresis separates molecules, especially DNA, based on their size and charge.

  • 2

    Restriction enzymes cut DNA into fragments, which are then loaded into wells in the agarose gel.

  • 3

    DNA fragments move towards the positive end of the gel, with shorter fragments moving faster and farther than longer fragments.
