 What is Electrophoresis in general?

Electrophoresis, according the Wikipedia is “the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field.” Expressed in layman’s terms, this can be translated to the definition: the movement of electrically charged particles in a fluid under the influence of an electric field. This phenomenon was observed first by Ferdinand Frederic Reuss in 1807. He noticed that the application of a constant electric field resulted in clay particles mixed in water to migrate.
The electrophoresis of positively charged particles is called cataphoresis. In a similar sense, the electrophoresis of negatively charged particles is called anaphoresis. Electrophoresis is used anytime a separation of molecules is needed. For example, DNA electrophoresis is used to study the genetic makeup of plants, animals, and humans. This is an analytical method used frequently in molecular biology and medicine as it is applied for the separation and characterization of nucleic acids, proteins, viruses, small organelles, and the likes.

  1. Thank for posting a missed day, and for doing online work. You should feel comfortable asking your mentor for ideas for this kind of activity. See me if you need some ideas.
