The drug Colchicine inhibits cell division by interfering with which process?
Show answer and explanation
Correct answer: Tubulin polymerization
Colchicine binds to tubulin dimers and prevents their assembly into microtubules. This disrupts the formation of the mitotic spindle, arresting cells in metaphase.
