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. Weba) Gel electrophoresis uses an electric field to move charged molecules through a gel matrix. In the case of DNA or RNA, the negatively charged phosphate groups of the nucleotides give the molecule an overall negative charge, causing it to move towards the positive electrode.
