In the DNA molecule, there are two strands which run anti-parallel: one in the 5' - 3' direction and other in the 3' - 5' direction, the two chains are held together by hydrogen bonds between their bases. Adenine (A), a purine on one chain is exactly opposite to thymine (T), a pyrimidine on the other chain. Similarly, cytosine (C), a pyrimidine lies opposite guanine (G), a purine. This allows a sort of lock and key arrangement between large sized purine and small sized pyrimidine. It is strengthened by the appearance of hydrogen bonds between the two.
