- . 2 3 1 4 . 5 6 I 7. .. (a) Identify the point in mitosis at which separase cleaves the protein complex that holds sister chromatid pairs together. In normal cells, separase is kept in an inactive state until it is needed. Explain how the progression of cells past sequential cell cycle checkpoints and the activity of enzymes such as separase is controlled by interactions between two major groups of regulatory proteins. (b) Identify an independent variable in the experiment graphed in Figure 1. Based on the data in Figure 1, identify a control that shows that Sepin-1 rather than something else in the culture medium is inhibiting the growth of the cancer cells. (c) Based on the data in Table 1, describe the general relationship between the sensitivity of cells to Sepin-1 and the concentration of separase in the cells. Use the Figure 1 data to calculate the ratio between the amount of Sepin-1 required to kill 50% of the cells in the cell line that is most sensitive to the compound and the…arrow_forwardA hypothetical poison prevents transcription factors from binding to the gene for tubulin proteins.

- During an experimental study, an investigator finds that the regulation of cell cycle and programmed cell death may be initiated by the mitochondrion. The interaction of the mitochondrion with the activation of the caspase family of proteases and subsequent apoptosis is most likely mediated by which of the following? (A) Calcium release (B) cAMP production (C) Cytochrome c release (D) GTP binding (E) Nitric oxide releasearrow_forward(B) Diagram the four phases of the cell cycle. (2 pt.)

(D) Name and describe the function of the four core cell cycle control complexes and indicate on the diagram above where they function in the cell cycle.arrow_forwardSome cancer drugs stop cell division by stabilizing microtubules so they cannot come apart. Which step of the mitosis is disrupted? A) Telophase B) cytokinesis C) Anaphase D) Metaphasearrow_forward
- Biopsies from aggressive cancers often have cells that contain several nuclei per cell when viewed through a microscope. Which scenario could explain how such a multinucleated cell might have come to be? (a) The cell underwent repeated mitosis with simultaneous cytokinesis. (b) The cell had multiple S phases before it entered mitosis. (c) The cell underwent repeated mitosis, but cytokinesis did not occur. (d) The cell underwent repeated cytokinesis but no mitosis. (e) The cell actually went through meiosis and not mitosis.arrow_forward1. (a) Describe the generalized model of the cell cycle. Demonstrate how cyclins and cyclin-dependent kinases can regulate the cell cycle. (b).

- Which of the following is true with respect to cyclins and CDKs? A) CDKs promote progression of the cell cycle, cyclins function to inhibit progression of the cell cycle B) CDKs are the checkpoints in the cell cycle, and when bound to cyclins, they stop progression of the cell cycle C) CDKs will only work to promote progression of the cell cycle when complexed with their designated cyclins D) CDKs are rarely expressed during a cell's cycle, unless cyclins are present to act as transcription factors .arrow_forwardThe anticancer drug paclitaxel (Taxol), derived from the Pacific Yew, has many effects on mitosis. One of its most powerful effects is that it prevents disassembly of the mitotic spindle, which prevents spindle fibers from shortening. Which phase of mitosis would this directly affect? Why would this stop cell division overall and lead to cell death?arrow_forwardA Patients with an inherited cancer have a mutation in a zinc-finger motif of P21 (a cell-cycle regulatory gene). Which of the following is the most likely result of this A) Decreased binding of a transcription factor to a DNA sequence B) Enhanced binding of hormones to receptors C) Enhanced transport of a hormone receptor complex into the nucleus D) Stimulation of mRNA synthesis E) "Unzipping" of leucine-rich helicesarrow_forward
