Question
While the filaments you saw in the simulations were all dynamic, there are situations where cytoskeletal filaments may not be dynamic. Which of the following would make a filament that was (at least temporarily) not changing?
The filament was in a cytoplasm with an extremely high concentration of monomers.
The filament was in a cytoplasm with an extremely low concentration of monomers.
The temperature was raised higher, so each monomer had more free energy.
The filament had a nucleation protein at one end and a capping protein at the other.
Explanation / Answer
In cytoplasm, there are three types of cytoskeletal filaments, which include microfilament, microtubule, and intermediate filaments. The filaments are made up of self-assembling proteins or monomers. The low and high concentration than critical concentration, favors monomer and polymer state respectively.
Based on the type of capping protein the actin filament either stabilizes or dissociates. The actin filament is the filament that is stable for some time.
Hence, the correct option among the following is last statement.
