The polymerization of pure G-actin in vitro proceeds in three phases.

    Column I

   Column II

A. nucleation phase

i. G-actin monomers exchange with subunits at the filament ends, but there is no net change in the total length of filaments

B. elongation phase

ii. marked by a lag period in which G-actin subunits combine into an oligomer of two or three subunits

C. steady-state phase

iii. the short oligomer rapidly increases in length by the addition of actin monomers to

both of its ends
