So we essentially extract a lambda DNA phage molecule from the lambda phage and we cut that molecule with restriction enzymes. And then we insert that DNA fragment into the lambda DNA phage molecule, the lambda phage DNA molecule. And so this is basically what we produce. So this orange section is basically part of that lambda phage DNA molecule. And this molecule has been inserted into that lambda phage molecule. And then we can follow that with each one of these molecules, we can create the following five recombinant DNA molecules.
