Electrophoresis is the process where small particles is drawn through a gel electrically from the negative pole to the positive. The smaller the particle, the faster it moves through the gel leaving a "blueprint' of what the substance is you're looking at. It is normally recorded on an xray, but can be recorded by pressing a piece of paper to the gel. That's paper electrophoresis. It is used on particles large enough to be viewed with the naked eye.

A method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules. An electric current is passed through a medium containing the mixture, and each kind of molecule travels through the medium at a different rate, depending on its electrical charge and size. Separation is based on these differences... Agarose and acrylamide gels are the media commonly used for electrophoresis of proteins and nucleic acids..and paper electrophoresis is a subset of this, when the separated out results are actually stained with an appropriate stain, such as methylene blue or ethidium bromide ( carcinogen), a paper is pressed against it, to reproduce the staining results. hope this answers the question..

Were you asleep in this class or just too lazy or dumb to answer it yourself or use a search engine?
