Instead of using this one, we use DDCT. So C, that means we have to count up the GS here, not including this one, because it's part of the primer. So we have one g, we have two GS. And that means we're going to have two complementary CS. So we're going to have two different fragments once again, one, two. And finally, if we use this one, we have to look for our adenine.
