The different types of nitrogen containing basesThe following four compounds are the nitrogen containing bases. (click on them to see, better, their structures, with animations): Adenine (A)
Adenine (A) pairs with Thymine (T), while Cytosine (C) pairs with Guanine (G). The amount of the bases in the global structure is well defined: it is always (A)=(T) and (G)=(C), hence (A)+(C)=(G)+(T) . |
