1.how staining cells with DNA dyes and flow cytometry allows for determination of cell cycle phase.
2.In the laboratory, you discover a mutation that destroys the kinase activity of the S-cyclin-Cdk complex. Do you predict that the cell will arrest in early G1, late G1,or G2 phases? Explain your answer, and draw the expected flow cytometry histogram of cells with this mutation, stained with PI, compared to normal control cells.
