And now we can take these recombinant DNA molecules and place them into those lambda phages, the bacteriophages, that are now ready to infect our bacterial cells. And so now we have this army of these unique lambda phages that each contain their own unique recombinant DNA molecule. And so in step five, we can actually take a bacteriophage, we can infect these lambda phase, we can infect those bacterial cells that equalize cells with these different types of lambda phages. And then essentially those bacterial cells will reproduce and will lice producing many, many copies of these different types of fragment DNA molecules. And so at the end, we essentially have these five beakers. And in each one of these five beakers, we have many copies of these lambda phages that each contain a specific type of DNA fragment.
