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...

MCAT - Lab Techniques (MilesDown) Native-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using NON-DENATURING conditions. Proteins keep their native charge and structure so they are separated based on charge and size. SDS-PAGE - correct answer A polyacrylamide gel electrophoresis method for proteins using DENATURING conditions. Sodium Dodecyl Sulfate denatures the proteins and gives the proteins a uniform charge. This allows them to be separated solely on mass,...
