And by a mechanism that we don't yet quite know, don't yet quite understand, the cell incorporates that complex, including that DNA, into the cell by some type of endocytotic process. Endocytosis, it's simply the process by which we have a receptor mediated process by which the cell invaginates and takes that into the cytoplasm of the cell. So basically, as shown in the following diagram, so we have that double stranded DNA molecule that we want to inject into our cell. We have this calcium phosphate solution that combines with the DNA to basically form a precipitate. And then the cell uptakes that molecule, including that recombinant DNA into the cell. And then that DNA is incorporated into the cell's genome inside the nucleus.
