The drug vincristine is used to treat many cancers. It apparently works by causing microtubules to depolymerize (breaksapart microtubules). Vincristine use has many side effects, including loss of dividing cells and nerve problem due to transportof neurotransmitter (required for neuronal functions) to proper locations. Explain why this might be so? How would youshow that the amoeboid cell movements are not caused by microtubules?
