Once a plasmid has … introduced into competent bacterial cells and the cells have grown into colonies on a medium selective for cells containing the plasmid, the next step is to perform a miniprep o f the plasmid DNA in preparation for DNA sequencing. The three steps are: 1) growing cells in liquid culture; 2) purifying the plasmid DNA from the culture; and 3) performing a restriction digest on the purified DNA to determine whether the DNA insert in the plasmid is the … size. To start the li...
