Answer» (A) (a) Gel electrophoresis (b) The separated fragments of DNA can be visualized only after staining with ethidium bromide followed by exposure to uv radiation. DNA will be visualized as bright orange coloured bands on the gel. (c) 500 bp migrate fast because it is the smaller fragment found nearer to anode than other fragments on the gel. |
