Answer:
The correct answer is - spindle fibers.
Explanation:
The colchicine is the chemical that obtains from the plant which is used to treat gout and joint swellings. Colchicine freezes the cell metaphase stage by inhibiting microtubule polymerization.
This inhibits the function of the tubulin enzyme that prevents the assembly of the mitotic spindle fibers which separates the chromosomes to opposite poles from the metaphase plate.
Thus, the correct answer is - spindle fibers.
