Worked practice questions
Which type of helix is observed in proteins?
- Only left-handed helices
- Both kinds in equal amounts
- No helices of any kind
- Only right-handed helices
Show answer and solution
Correct answer: D. Only right-handed helices
Helical portions of protein chains are always right handed.
The arrangement of separate folded subunits relative to one another is which protein structure?
- Quaternary structure
- Tertiary structure
- Secondary structure
- Primary structure
Show answer and solution
Correct answer: A. Quaternary structure
The architecture formed by assembling several polypeptide subunits is the quaternary structure.
