Describe what would happen if you conducted an electrophoresis of a mixture of arginine, alanine, and aspartic acid, using a buffer with pH of 7.0. Should you place the mixture of amino acids at one end of the starch gel or in the middle? A diagram may help.
**I know that smaller peptides migrate fastest so Alanine, aspartic acid, then arginine, but I'm still very confused.
