#Unit 2. Cellular Organization
  1. Actin can reversibly assemble into filaments that consist of two helices of actin subunits.
  2. Within the filament, the subunits are positioned with their nucleotide-binding cleft directed toward the plus end.
  3. As the concentration of actin monomers declines, the system approaches a steady state.
  4. The lag phase in filament growth is eliminated if preexisting seeds are added to the solution.
