The phenomenon that illustrates the dynamic behavior of actin filaments and is critical to regulating the structure and function of actin filaments is known as
A) assembly.
B) dynamic instability.
C) treadmilling.
D) disassembly.

Question

Quizplus · Accepted Answer

Treadmilling is the process of actin filaments undergoing dynamic behavior by adding subunits to one end while simultaneously removing subunits from the other end. This is critical in regulating the structure and function of actin filaments within cells. Assembly, disassembly, and dynamic instability are all related to actin filaments, but do not specifically describe the process of treadmilling.
