The central part of an anisotropic band where the only thick , filament is present and thin filament is absent is called 'A' band. III.

Name the three proteins present on the thin myo-filament

Consider the diagram of thin myofilament. Now, read carefully the statements about molecular arrangement of actin and myosin in the filament. I. Each actin (thin filament ) is made up of 2 F-(filamentous) actins. II. F-actin is the polymer of G-(globular) actin. III. Two-F-actins are twisted into a helix. IV. Two strands of tropomyosin run along the entire length of F-actin. Choose the correct option.
