Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa.

What is an example of A complementary base pairs?

Guanine and cytosine are bonded together by three hydrogen bonds; whereas, adenine and thymine are bonded together by two hydrogen bonds. This is known as complementary base pairing.

Does complementary base pairing?

The standard arrangement of bases in nucleotides in relation to their opposite pairing, such as thymine being paired with adenine and cytosine paired with guanine.
