The figure belоw is а mаp оf the plаsmid pGEN 101. The plasmid is 20 kb, which stands fоr kilobases, or thousands of base pairs. It shows the restriction sites for two different enzymes--BamHI and EcoRI--and the resulting fragment sizes. Study this figure to understand what this means. You can use the results of electrophoresis to determine which restriction enzyme was incubated with the plasmid DNA. There is only one restriction site for the enzyme EcoRI. Imagine the result of mixing this plasmid with EcoRI. The circular plasmid would be cut open, resulting in a single large linear fragment of DNA that would be 20 kb in size. Lane 2 shows a piece of DNA that is 20 kb and so must have been digested with EcoRI. Which lane shows a digest with only the restriction enzyme BamHI?
