Diameter of thick filament is____________?
Correct answer: C. 16nm
- A. 7 nm.
- B. 8 nm
- C. 16nm
- D. 10-100 ?m.
Explanation
A thick myosin filament has a diameter of about 15 to 16 nm, so 16 nm is the appropriate value. Students may choose 7 nm because thin actin filaments are about 7 nm in diameter, while 10 to 100 micrometres is far too large for a filament.
