Input (English): This technique can be followed up by ethidium bromide staining which allows easy visualization of the resulting bands. The namesake component in this procedure must be covered with tris acetate buffer and ladders must be placed in the end wells to allow comparison. Polyacrylamide may used to produce the matrix when the samples are small, though agarose is more commonly used. For 10 points, identify this technique wherein an electric field separates DNA molecules according to size as they travel to the positive electrode.
Output (English): Science
