Unformatted text preview: D. Control to show that many live E. coli cells were plated and can grow in the absence of antibiotics. E. Facilitates the movement of plasmids into the cells. F. Allows plasmids to replicate,which amplifies their genes. G. Binds to DNA and fluoresceses in UV radiation so DNA bands can be seen on a gel. H. These ascertain the effectiveness of the antibiotics used and establish that they are not resistant to these antibiotics. I. Helps determine the size of Ampr and Kanr plasmids. J. Determine the types and composition of plasmids contained by a colony (clone) of cells growing on a double antibiotic plate. K. Select for cells that have resistance genes for both antibiotics. L.
