Why do you need a molecular weight ruler alongside your samples during electrophoresis?
A molecular weight ruler uses a sample of fragments of a known size (known as a molecular weight marker) to be placed alongside the experimental and control samples. It helps compare the migration distance of the experimental fragments to the migrating distance of the fragments of a known size that make up the molecular weight marker. Then the scientist can calculate an approx. size of their experimental samples.
