RNA molecules in living cells form what look like liquid droplets formed by liquid/liquid phase separation. But unlike the molecules in conventional phase separating mixtures, RNA molecules are transported by molecular motors that consume energy and so are out of equilibrium. Motivated by this we consider what sort of simple rules for the dynamics of model mRNA molecules lead to liquid/liquid phase separation. We find that dynamics that slow as the local density of molecules increases, drive…

Physical principles of intracellular organization via active and passive phase transitions

The way in which equilibrium thermodynamic driving forces may interface with the fundamentally out-of-equilibrium nature of living cells and time and/or space-dependent concentration profiles may modulate the phase behavior of biomolecules in living cells is discussed.
