Formin protein nucleate the assembly of unbranched filaments, (FH1 and FH2 domains-Actin nucleation by the formin FH2 domain).

Formins are activated by membrane-bound Rho-GTP, a Ras-related small GTPase.

The Arp2/3 Complex Nucleates Branched Filament Assembly.

In electrophoresis because of the varying charges and masses, of different molecules and particles of a mixture will migrate at different velocities under uniform force and will thus be separated into single fractions.

When the potential gradient E is applied, the force F on a molecule bearing a charge of Q  sepreated  by distance d (measured in coulombs) is                  (in newton).
