Worked Solution & Example Answer:The diagrams below represent examples of three levels of structure with respect to the folding and assembly of a protein - VCE - SSCE Biology - Question 1 - 2015 - Paper 1
Step 1
Complete the table below to indicate the diagram that represents the structural level of the protein given.
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.
