Answer

The diagrams can be identified as follows:

  • Primary: Diagram C represents the primary structure of a protein as it shows a polypeptide sequence without any folding.
  • Secondary: Diagram A represents the secondary structure of a protein as it illustrates the alpha-helix formation which is a common structural motif.
  • Tertiary: Diagram B represents the tertiary structure of human interferon as it shows the overall 3D conformation of the protein.

Step 2

Name the molecular sub-unit of a protein.
