Some Anticancer Chemotherapy Agents Interfere with Microtubules

Question

Some anticancer chemotherapy agents interfere with microtubules. How do they work?
A) They inhibit the mitotic spindle and prevent cell division.
B) They inhibit the contractile ring and prevent cell division.
C) They inhibit telophase, because microtubules are required to form nuclear envelopes.
D) Microtubules replicate DNA, so they inhibit chromosome duplication.

Accepted Answer

Microtubules are essential for the formation and function of the mitotic spindle during cell division. Anticancer agents that interfere with microtubules typically prevent the spindle from properly forming or functioning, thereby inhibiting cell division. This is a key strategy in cancer treatment, aiming to stop the proliferation of cancer cells.
