So to see what we mean, let's take a look at the following diagram. So let's suppose that this is the complementary sequence to this gene here. And so this is the three n, because this is the five end and this is the five n here. And what that means is as the RNA polymerase moves along this DNA molecule, it essentially stops here and it begins transcribing that complementary template, that DNA molecule. And as it transcribes that molecule, it will continue forming that RNA molecule until it reaches this termination sequence. Now, it will form that termination sequence, but once it forms the termination sequence, that termination sequence encodes for a signal we call a hairpin.
