Which of the following organic molecules may have up to four levels of structure?

Proteins have up to four levels of organic structure.

1.Primary structure -  the linear arrangement of amino acids.

2. Secondary structure - areas of folding or coiling within a protein.

3. Tertiary structure - the final three dimensional structure of a protein.

4. Quaternary structure - non covalent associations that bind multiple polypeptides into a single larger protein. E.g.  hemoglobin has four polymers, two alpha and two beta chains. They are non covalently bound to each other to form a single large protein - hemoglobin.

answer: c.

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
