The ampicillin resistance gene (AmpR) is called a selectable marker gene and is incorporated into several plasmids that are commonly used in a wide range of genetic engineering and molecular biology experiments.
Due to a mishap in the lab, bacteria carrying a plasmid with an ampicillin resistant gene and bacteria carrying a plasmid with a gene that provides resistance to another antibiotic (kanamycin) were accidentally mixed together. Design an experiment that will allow you to sort out the two kinds of bacteria.
