Resonance structures refer to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure. The Lewis dot structures show valence electrons.

Hydrogen bonding
The cohesion between strands of the DNA double helix and the primary structure of proteins are both dependent on hydrogen bonding.
There are several types of bonds that can have a crystallized structure. These include ionic bonds, covalent bonds, and metallic bonds. The crystal structure is an arrangement of atoms and molecules.
Atoms do not form molecules through ionic bonding. They form molecules through covalent bonding, in which the atoms share electrons.
The molecules haves secondary types of bondings as 1- Dipole-Dipole interaction, 2- Vander waal's bonding and 3- Hydrogen bonding, depending upon nature of molecules.
Proteins and DNA.

Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.
The backbone of a polypeptide could be represented by a chain of nitrogen and hydrogen atoms. The polypeptide backbone is the key contributor to protein secondary structure, which involves backbone-to-backbone hydrogen bonding.
The structure of water is such that the molecules are held together by hydrogen bonding, and the geometry of the water molecule is a bent structure. This hydrogen bonding gets stronger as the temperature gets lower. Ice has a crystalline structure such that the atoms are organized in a simple repeating structure. The crystalline structure of ice is a repeating arrangement of eight molecules of water. Ice becomes less dense that liquid water, and that's why it floats. But by the same token, it expands to take up more space.
