Students have asked these similar questions
(a) the cell cycle is divided into different phases (referred to as M, G0, G1, S and G2); Can you account for what happens during the different parts of the cycle and out of it is checked? ( b) What is the difference between apoptosis and necrosis? ( c) What are caspases and what is their function in the cell?

(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…

Which scenario could explain how such a multinucleated cell might have come to be? (a) The cell underwent repeated mitosis with simultaneous cytokinesis.

- 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_forward(46) A mutated form of protein p5x is found in patients with squamous cell carcinoma.
