Default DNA Analysis by Gel Electrophoresis?



You and your lab partner have just loaded your digested DNA into the wells of the agarose gel. You
took all the precautions to insure it would work well such as loading the dye and not reusing tips. Since
your gel has to run for 45 min, you and your partner decide to get lunch. After 30-min you return and look
at your gel to see how much longer you need to run it. To your shock, you see no dye running down the
length of your gel. Explain how this could have occurred.

It might be problem of power supply or due to wrong % gel.
