Скачать или смотреть Agarose Gel Electrophoresis

Please note my mistake in describing the anode as negatively charged (and the cathode as positive). The opposite is correct: the cathode is negative; the anode is positive. This doesn't impact the accuracy of the description, though: the positive charge is placed at the end of the gel away from where the DNA is loaded, so that the negatively charged DNA migrates through the gel toward the positive terminal.
