The molecular-based method used by the scientists to differentiate between the species of daisies was gel electrophoresis. Gel electrophoresis is a technique used to separate charged molecules such as DNA, RNA, and proteins by their sizes. To begin with, samples are loaded at the top of the gel in the same horizontal position. Once the samples are loaded, an electric current is applied, which allows the charged molecules to migrate to the opposite end. For example, negative charged molecules will migrate towards the positive end. As the charged molecules are pulled from one end to another, smaller molecules migrate more quickly than larger molecules, thus allowing them traveling further than larger fragments. As a result, the molecules will
