Which of the Following Is False About Dynamic Instability of a Microtubule

Multiple Choice

Which of the following is false about dynamic instability of a microtubule end?

A) During a growth phase,assembly of GTP-tubulin is faster than incorporated GTP is hydrolyzed,forming a GTP-cap.
B) During a catastrophe phase,hydrolysis of incorporated GTP is faster than GTP-tubulin addition,forming a GDP-cap.
C) During rescue,GTP-tubulin assembles fast enough to reestablish a GTP cap.
D) Each end of a microtubule can undergo dynamic instability independently.
E) A,B,C,and D are true.
