Tertiary structure
Quaternary structure
2. Alpha-helices and beta-pleated sheets are examples of which level of protein structure?
Primary structure
Secondary structure
Tertiary structure
Quaternary structure
3. The overall three-dimensional shape of a single polypeptide chain is referred to as its structure.
4. When two or more polypeptide chains come together to form a functional protein, it exhibits structure.
