The following statements describe SDS-PAGE, a method used to separate proteins. Select the true statements. Assume that SDS-PAGE is performed under reducing conditions. A.A protein binds roughly 1.4 times its mass of SDS resulting in a large overall negative charge. B.SDS-PAGE utilizes agarose gel to separate proteins. C.Smaller proteins migrate faster through the polyacrylamide gel. D.Sodium dodecyl sulfate binds proteins, resulting in protein-SDS complexes that are similar in size. E.Protein-SDS complexes migrate toward the positive electrode. F. Proteins are visualized using a dye that binds to the gel matrix, but not to proteins
