And so as the RNA polymerase travels along the double strand DNA molecule it doesn't use this molecule as the template, but it uses the complementary DNA strand as the template. So if we look at the complementary strand for this particular molecule, it will basically begin on the three end and at the five end. And it's that particular DNA molecule that the RNA polymerase uses as its template. So once again, in this diagram, this is not the template, but the complementary sequence to this DNA molecule is that template. That the RNA molecule, the RNA polymerase actually uses. Now let's move on to eukaryotic cells.
