The graph below shows the relative amoun 6 (dcz7zqkz8dc2 +rofpe1oy ;t of Dp7-qfqunh5 q9.yctht5nv klg y6. +n3NA in one cell during one complete cell cycle. Each lette5-c+qntyh3p fqn .79tq h. glnu5yk6vr represents one stage of the cell cycle.


1.1.State which stage of mitosis or interphase is represented by stage B in the graph.

1.2.Explain your answer to part (i).

1.3.Bortezomib is an anticancer medication and arrests cells in the G$_2$ phase. If a cell shown in this graph began the cell cycle at A with 3 relative units of DNA, and Bortezomib was applied to the cell culture at stage A as well, estimate the relative amount of DNA in the cell at the end of C.

2.Explain why the amount of DNA in one cell remains the same in stages C and D.


3.The diagram above shows cells in different stages of mitosis. Label one cell that is in prophase and one cell that is in anaphase.
