So let's suppose we take this cell that carries this plasmid and we take this cell and we place it onto a petri dish that has a nutritious substance. And what happens is this cell now divides via binary fission, producing millions and millions of these bacterial cells that have identical copies of these plasmids. And we follow the same exact step with the second type of cell that contains the second plasmid. Then we follow that with the third cell that contains the third plasmid and the fourth cell that contains this fourth plasmid. And so at the end of the step, what we have is a colony that consists of millions of millions of these identical plasmids. And we have a colony for each and every one of these different types of cells.
