The left-most graph is a FACS profile of an asynchronously dividing population of cells. These cells have a total cell cycle length of 20 hrs, a G1 phase that is 12 hrs, and an S-phase that is 6 hrs. How would the FACS profile look under the following conditions? Draw your answer on the corresponding empty graphs labeled (A), (B), (C) and (D). A) deprive the cells of nutrients (serum starvation) for 24 hr. B) treat the cells with colchicine (a microtubule-destabilizing drug) for 24 hr. C) deprive the cells of nutrients for 24 hr followed by addition of nutrients for 16 hr. D) treat cells with staurosporine (an apoptosis-inducing drug) for 48 hr.
