Which level of protein structure is characterized by the overall 3D shape of a single polypeptide chain?
Correct Answer: tertiary structure
- Step 1: Understand that proteins are made of long chains called polypeptides.
- Step 2: Know that these polypeptides fold into specific shapes.
- Step 3: Identify that the 3D shape of a single polypeptide chain is called its tertiary structure.
- Step 4: Recognize that the tertiary structure is determined by interactions among the side chains of the amino acids in the polypeptide.
