Answer 2

OPTION C IS THE CORRECT answer

Treadmilling of actin filaments in the steady state occurs at G-actin concentration:

• (a) Below the Cc of the (-) end
• (b) Above the Cc of the (-) end but below the Cc of the (+) end
• (c) Above the Cc of the (+) end but below the Cc of the (-) end
• (d) Above the Cc of the (+) end

EXPLAINATION

• At a G-actin concentration above Cc, there is net growth of filaments; at concentrations below Cc, there is net depolymerization of filaments.
