Kinetochore is the proteinaceous covering of centriole, to which spindle fibers attach.

Correct Option: B

Kinetochore is the proteinaceous covering of centriole, to which spindle fibers attach.

Colchicine inhibits spindle formation, due to which chromatids are unable to separate during anaphase which results in doubling of chromosomes. So, if a diploid cell is treated with colchicine, there is doubling of chromosomes and it becomes tetraploid,. Its an alkaloid obtained from Colchicum autumnale.
