Answer:
Colchicine inhibits the formation of the microtubules or spindle fibers. Without the spindle fibers the chromosomes cannot move to the poles.
Step-by-step explanation:
Spindles and microtubules are both important components of cellular division. The structures go hand in hand with each other and are necessary for cellular division to occur.
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle and it is called meiotic spindle during meiosis,
