And the bacterial cell will essentially use its ribosomes, its cell machinery to synthesize the proteins that are encoded by that particular gene. And then we can extract and collect and study those proteins from that bacterial cell. Now, what's one application of this method? Well, instead of using prokaryotic genes, we can also use eukaryotic genes. And this is especially important in a field of medicine where in medicine we're able to use this procedure to basically synthesize any protein, any enzyme that we want to. And that's exactly what allows patients with, let's say, diabetes to essentially survive for a very long time because they now have a way to obtain these proteins which are synthesized in the lab via this procedure.
