It is a polar molecule due to the presence of the carbonyl (C=O) and amino (NH₂) groups. The aromatic rings in guanine's structure make it a relatively stable molecule, but it can still undergo ...

This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...
