Colchicine is a drug that binds to the protein that forms microtubules, thereby preventing microtubules from forming. Colchicine has been used to study mitosis because it stops the process. Most likely this is due to
A. prevention of cell-plate formation.
B. prevention of kinetochore formation.
C. inhibition of DNA synthesis
D. alteration of centriole structure
E. prevention of sister chromatid formation
