The cell cycle-specific agent vincristine sulphate (Oncovin) acts in which phase of the cell's life cycle?
a. S phase
b. Mitotic phase
c. Phase G1
d. Phase G0
ANS: B
Vinca alkaloids block the formation of the mitotic spindle during mitosis, thus inhibiting cell division. The S phase is the stage of active synthesis of two sets of DNA. Phase G1 is considered a presynthetic phase in which the cell prepares for DNA synthesis by manufacturing necessary enzymes. G0 is the largest variable in the cell cycle and, during this resting phase, the cell is not actively replicating.
