Which level of protein structure is characterized by the arrangement of multiple polypeptide chains?

Correct Answer: Quaternary structure

Step 1: Understand that proteins are made up of smaller units called polypeptides.
Step 2: Know that polypeptides are chains of amino acids linked together.
Step 3: Learn that proteins can have different levels of structure: primary, secondary, tertiary, and quaternary.
Step 4: Identify that the quaternary structure is the highest level of protein structure.
Step 5: Recognize that the quaternary structure involves the arrangement and interaction of multiple polypeptide chains.
