Gel Electrophoresis Questions and Answers Graded A+ What is the relationship between gel concentration and the size of molecules being separated? Higher gel concentrations create smaller pores, which are more effective for separating smaller molecules, while lower concentrations allow for the separation of larger molecules. Describe how gel electrophoresis can be used to determine the purity of a DNA sample. By running a gel electrophoresis, one can observe the banding pattern of a D...
