Cells that have NOT undergone transformation with pGFP should be killed after plating  on LB-AMP.  

The following gel shows the results of a crime scene investigation.  Lane 1 shows a DNA sample that was obtained from the scene of a crime (there was evidence of the criminal cutting himself, so it’s the criminal’s blood sample that produced the DNA bands in lane 1).
