What might a scientist observe when looking at cancer cells?

¿Qué podría observar un científico cuando observa las células cancerosas?

• Cancer cells will become stuck in the G1 on phase and will not enter the S phase

  Las células cancerosas se atorarán en la fase G1 en fase activa y no entrarán en la fase S

• Cancer cells will go through the S phase twice

  Las células cancerosas atravesarán la fase S dos veces

• Cancer cells will continuously repeat the cell cycle because their growth is unregulated and will not enter a resting phase of G0

  Las células cancerosas repetirán continuamente el ciclo celular y no entrarán en una fase de reposo que es G0

• Cancer cells will not undergo cytokinesis

  Las células cancerosas no sufrirán citocinesis.
