b) Has no growth factor receptors on its surface.

c) Cyclin B is present, the spindle is present and chromatin is completed condensed.

d) Cyclin B is absent, separase is active, and kinetochore microtubules are shortening.

e) The cell can be strongly labeled by adding up fluorescent deoxynucleoside triphosphates to its culture medium.
