Activation of which of the following is associated with the formation of focal adhesions and stress fibers?
A)Rho
B)Ras
C)Cdk-42
D)intermediate filaments
E)γ-tubulin

Question

Quizplus · Accepted Answer

Rho is a GTPase protein that plays a key role in the cytoskeletal organization of focal adhesions and stress fibers by regulating actin cytoskeleton dynamics. When Rho is activated, it triggers the formation of actin stress fibers and associated focal adhesions. Therefore, activation of Rho is associated with the formation of focal adhesions and stress fibers. The other options listed are not directly involved in the formation of focal adhesions and stress fibers.
