5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.
