A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 8 picograms of DNA per nucleus. How many picograms would be found at the end of S and the end of G2 ?  \na. 8; 8 b. 8; 16 c. 16; 8 d. 16; 16 e. 12; 16  \n  2. Why do chromosomes coil during mitosis?  \na. to increase their potential energy  \nb. to allow the chromosomes to move without becoming entangled and breaking  \nc. to allow the chromosomes to fit within the nuclear envelope  \nd. to allow the sister chromatids to remain attached  \ne. to provide for the structure of the centromere  \n  3. A plant–derived protein known as colchicine can poison cells by blocking the formation of the spindle. Which of the following would result if colchicine is added to a sample of cells in G2 ?  \na. The cells would immediately die.  \nb. The cells would be unable to begin M and stay in G2.  \nc. The chromosomes would coil and shorten but have no spindle to which to attach.  \nd. The chromosomes would segregate but in a disorderly pattern.  \ne. Each resultant daughter cell would also be unable to form a spindle.  \n  4. What causes the decrease in the amount of cyclin at a specific point in the cell cycle?  \na. an increase in production once the restriction point is passed  \nb. the cascade of increased production once its protein is phosphorylated by Cdk  \nc. the changing ratio of cytoplasm to genome  \nd. its destruction by a process initiated by the activity of its complex with a cyclin  \ne. the binding of PDGF to receptors on the cell surface  \n  5. Which of the following is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?  \na. PDGF b. MPF c. Cdk d. cyclin e. protein kinase   6. Which of the following is a protein maintained at constant levels throughout the cell cycle that  \nrequires cyclin to become catalytically active?  \na. PDGF b. MPF c. Cdk d. cyclin e. protein kinase  \n  7. The cyclin component of MPF is destroyed toward the end of which phase?  \na. G0 b. G 1 c. S d. G2 e. M  \n  8. The MPF protein complex turns itself off by  \na. activating a process that destroys cyclin components.  \nb. activating an enzyme that stimulates cyclin.  \nc. binding to chromatin.  \nd. exiting the cell.  \ne. activating the anaphase–promoting complex.  \n  9. Density–dependent inhibition is explained by which of the following?  \na. As cells become more numerous, they begin to squeeze against each other, restricting their size and ability to produce control factors.  \nb. As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they stop dividing.  \nc. As cells become more numerous, the protein kinases they produce begin to compete with eachother, such that the proteins produced by one cell essentially cancel those produced by its neighbor.  \nd. As cells become more numerous, more and more of them enter the S phase of the cell cycle.  \ne. As cells become more numerous, the level of waste products increases, eventually slowing down metabolism.  \n  10. Cells from an advanced malignant tumor most often have very abnormal chromosomes, and often an abnormal total number of chromosomes. Why might this occur?  \na. Cancer cells are no longer density dependent.  \nb. Cancer cells are no longer anchorage dependent.  \nc. Chromosomally abnormal cells can still go through cell cycle checkpoints.  \nd. Chromosomally abnormal cells still have normal metabolism.  \ne. Transformation introduces new chromosomes into cells.  \n  11. All cell cycle checkpoints are similar in which way?  \na. They respond to the same cyclins.  \nb. They utilize the same Cdks.  \nc. They give the go–ahead signal to progress to the next checkpoint.  \nd. They each have only one cyclin/Cdk complex.  \ne. They activate or inactivate other proteins.  \n  12. A research team began a study of a cultured cell line.
