    Cortical microtubules in plants are rigid rod-like biopolymers attached by their ends to the cell wall. Microtubules organize in a two dimensional structure forming part of the cytoskeleton. Each individual microtubule is a highly dynamic self-assembled rod, which is permanently growing or shrinking. A key property which allows for such dynamic behavior of microtubules is the dynamic instability. Periods of constant growth from one end are interrupted by rapid depolymerization, which in turn, changes to constant growth.

Slow degradation shifts the equilibrium size distribution of block co-polymer micelles and changes their properties. The quasi-equilibrium ...
