Describe the significance of the secondary and tertiary structures of a protein

Biomolecular structure is the intricate folded, three dimensional shape that is formed by a protein, DNA, or RNA molecule. It is important to its own function. The structure of these molecules are frequently decomposed into primary structure, secondary structure, tertiary structure, and quaternary structure. They are the waste and decomposition of the biomolecular structure.
