∙ 15y ago
If meaning the four structural levels in proteins, then these are:
* Primary structure, which is the sequence of amino acids in the peptide chain that constitutes the protein. * Secondary structure, is the location of formations called alpha-helices, beta-sheets and coiled coils (undefined, flexible structure), that forms with the help of hydrogen bonds between amino acids. * Tertiary structure: This is the over-all fold/structure of one peptide chain/protein, which can consist of many so called "domains" of typical structures of alpha-helices and beta-sheets. * Quaternary structure: Because some proteins are formed from many smaller subproteins (that is, by many peptide chains), quaternary structure describe how these subunits are assembled together.

The primary structure is just the sequence of the DNA.
Secondary structure refers to alpha helix and beta sheets.
Tertiary structures is the overall shape of a single protein(which is a result of the interactions of primary and secondary structures).
Quaternary structures are from from the interaction of multiple proteins

What are the four major macromolecules necessary for life their functions and component structures?
Carbohydrates, Lipids, Nucleic Acids, and Proteins, which are also known as inorganic compounds.
What are four names of macromolecules?
Macromolecules are very large molecules. The term is used for the four biopolymers nucleic acids, proteins, carbohydrates and lipids. It is also used to describe non-polymeric molecules - such as macrocycles.

What role does DNA play in an organism?
DNA is composed of four deoxyribonucleic acids. The sequence of these determines the sequence of amino acids in proteins. Proteins are essential in maintaining and multiplying cells. Additionally DNA is structured in such a way that it can be copied exactly when the cell prepares to divide.
