WebDNA Gel Electrophoresis Introduction & Overview. Electrophoresis is a technique where similarly charged molecules in a mixture flow in the same direction using an electric field, and the molecules are separated based on size. In this method, separation of the molecular components of the mixture is strictly based on size (molecular weight). Webin the slots BEFORE the hot, melted gel is poured. After the gel solidifies, the comb is taken out. The "teeth" of the comb leave small holes in the gel that we call "wells." wells Wells are made when the hot, melted gel solidifies around the teeth of the comb. The comb is pulled out after the gel has cooled, leaving wells. newest ratchet a
