Question

Each actin filament is made of

• A. 2 'G' Actin molecules
• B. 2 F Actin molecules
• C. 1 F Actin molecules
• D. 1 G Actin molecules

Answer 1

The correct option is B 2 F Actin molecules

Actin is the protein which helps in the muscle contraction. It present in two forms G actin (globular actin) and F actin (filament actin). In muscles, actin filament is formed by the two long strand of bead-like twisted actin molecule.

So, the correct answer is '2 F Actin molecules'.
