What are the primary, secondary, tertiary, and quaternary structures of proteins?

• Proteins do not have primary, secondary, tertiary, and quaternary structures

• Primary, secondary, tertiary, and quaternary structures are only found in DNA

How does the structure of a protein determine its function?

• The function of a protein determines its structure.

• The structure of a protein is not related to its function.

• Proteins do not have a specific structure that determines their function.

• The structure of a protein determines its function.
