Taxol is a drug that comes from the bark of a tree that binds and irreversibly stabilizes microtubules. It is often used during chemotherapy to kill dividing cancer cells. How does taxol block cell division?
A-

D-
Taxol prevents spindle formation and separation of chromatids.
Answer: D-
Taxol prevents spindle formation and separation of chromatids.
Explanation:
The Taxol is used as an anticancer drug formulation. It is obtained from yew tree. An anticancer drug affects the cell cycle machinery so as to limit the production of cancer cells. This drug ceases the microtube formation in animal cells. This prevents the spindle fiber formation and further prevents the mitosis of cancerous cancers as the chromosomes will not separate apart and so abnormal cells will not produce further.
