During cell division, the failure of enzymes to detach cohesin molecules fro- elect one: A. more DNA than the parent cell B. less DNA than the parent cell C. can be both more DNA than the parent cell or can be less DNA than th the same amount of DNA as the parent cell

Which phase of the cell cycle is NOT part of interphase? Group of answer choices A. G1 B. S C. M D. G2

Match the stage of the cell cycle or the phase of mitosis with the event or cellular process that is happening in that stage/phase.                                                             S                                                             telophase                                                             prophase                                                             metaphase A. falling levels of cyclin B. chromosomes condense into (microscopically) visible sister chromatid arms C.

2.) One experimental tool used in the biological research and in clinical settings is called Fluorescent Activated Cell Sorting (FACS) or cell cytometry. For example, a cell membrane permeable (or nonpolar) chemical called Hoescht 33342 dye will specifically label DNA. Interpret the graph (Figure 17-4) that illustrates normal cells that have been labeled with Hoescht 33342 dye, and assign which phase(s) of the cell cycle (G1, S, G2, or M) corresponds to the fluorescence intensity. Justify your answers. 1 relative fluorescence per cell Figure 17-4 Analysis of Hoechst 33342 fluorescence in a population of cells sorted in a flow cytometer (Problem 17-15). number of cells

Cancer, the uncontrolled growth of cells, often results in a tumor, or mass of abnormal cells. Some cancerous tumors consist of many cells that are much smaller than normal. According to Figure 1, what part of the cell cycle is most likely being affected? Explain.
