Colchicine is an inhibitory chemical, which

Correct answer: C. Prevents the spindle formation in mitosis

  • A. Stops the functioning of centriole
  • B. Prevents attaching of centromeres with rays
  • C. Prevents the spindle formation in mitosis
  • D. Prevents the formation of equatorial plane

Explanation

Colchicine is an alkaloid that inhibits spindle fiber formation during mitosis, preventing proper chromosome segregation during anaphase. This disruption can result in cells with multiple sets of chromosomes, a condition utilized in research and therapy. While centrioles and centromeres are involved in the mitotic process, colchicine's primary action is on the spindle fibers themselves, not directly on these structures, which is why Option C is correct. Other options incorrectly attribute its action to different cellular structures or processes.
