Compared to the normal situation, in which actin monomers carry ATP, what do you predict would happen if actin monomers that bind a nonhydrolyzable form of ATP were incorporated into actin filaments?

• A)Actin filaments would grow longer.
• B)Actin filaments would grow shorter because depolymerization would be enhanced.
• C)Actin filaments would grow shorter because new monomers could not be added to the filaments.
• D)No change, as the addition of monomers binding nonhydrolyzable ATP would not affect actin filament length.
