So that means this is where we cleave it. And if we use this same restriction enzyme and this same DNA molecule, we can insert it into this region. And so we produce the following plasmid. Now, notice, because the plasma contains this insertion inside the green gene, this green gene is now inactivated. But because the blue gene does not contain any insertions, it still is able to actually produce that protein. That gives the cell the ability to resist the antibiotic tetracycline.
