So this seed can be detected by creating and adding a radioactively labeled complementary DNA strand to that polymer sheet. Since it is complementary to the gene of interest, it will hybridize with the fragment of interest. So it will basically form a double stranded, form a double stranded helix. So, to see exactly what we mean, let's take a look at the following diagram. So in this diagram, it is before we added that DNA probe. And so if we zoom in on this band, band C, we basically get this double stranded DNA molecule has been denatured.
