Gel Electrophoresis is a technique used to separate Correct Answer: DNA fragments and other macromolecules by size and charge DNA samples are loaded into wells/indentations at one end of a gel and an electric current is applied to pull them through the gel DNA fragments are negatively charged, so they move towards the positive electrode Because all DNA fragments have the same amount of charge per mass, small fragments move through th egel faster than large ones In Gel Electrophoresi...
