    DNA. It is a sign of the success of a bacterial transformation experiment. Escherichia coli (E. coli) is a common bacterium that makes single celled plasmids exchange easy. It yields clones so that the DNA will not be mixed up. In this experiment students attempt to transform E. coli with a plasmid. The plasmid that will be used to transform the bacteria in this experiment is pGal and occurs naturally in E. coli. Transformed bacteria cells will grow in the presence of the antibiotic while bacteria
