Base Pairing

The fundamental property of DNA that renders it the ideal genetic material is that of complementarity. Two nucleotides that can form a base pair are said to be complementary to one another. Pairing between complementary bases, with adenine pairing with thymine and guanine pairing with cytosine, is achieved by hydrogen bonds, shown as blue dashed lines.
