There should be two H's, not one H right over here. And this should have an H, and this should have an H. Okay, so this here is the five prime N, and this here is the three prime N. And notice, just like in proteins in nucleic acids, we also have polarity. So the five N is polar because we have this negative two charge as a result of the phosphate. And this N is also polar because we essentially have this oh group. And so that's exactly why we have polarity along our nucleic acid. So nucleic acids have polarity.
