And these are the interactions that basically exist between our bases. So we have guanine forms three hydrogen bonds with cytosine. This is one, two, three, and adenine forms only two of these hydrogen bonds. And what that basically means is if our DNA molecule contains a higher amount of guanine cytosine bases compared to adenithiamine, that means our DNA molecule will be more stable, because this base pair contains three H bonds, but this base pair only contains two H bonds. Now, the final thing that I'd like to briefly talk about is what actually holds and stabilizes that double helix structure. Well, number one are these hydrogen bonds that exist between our base pair.
