Expert

Verified

To form DNA molecule, purine bases join to pyrimidine bases by intermolecular bonds termed as hydrogen bonds. Hydrogen bonds take place whenever there is hydrogen near one of such electronegative elements: fluorine, oxygen and nitrogen.

In such situations hydrogen appears as like having lost electrons for such elements and a very strong polarization is made. The extremely positive hydrogen attracts pairs of electrons of other molecules forming a hydrogen bond.
