Regulating physical size is an essential problem that biological organisms must solve, but it is not well understood what physical principles and mechanisms organisms use to sense and regulate their size.

Proteins from the kinesin-8 family promote microtubule depolymerization, a process thought to be important for the control of microtubule length in living cells.

Helicases are molecular motors that unwind double-stranded nucleic acids. Here we model a helicase motor that can switch between two states, which could represent two different points in the ATP hydrolysis cycle.

his paper presents a theoretical study of the coupling between helicase translocation and nucleic acid unwinding.
