This is a protein model that can be assembled (polymerized) in an analogy to what happens inside living cells.
Actin is a protein involved in maintaining a cell's shape, as part of what's called the cytoskeleton. Actin exists as monomers, but certain conditions (like the actions other proteins, or the presence of certain salts) cause the monomers to stick together and create these long, helical filaments.
