Which of the following can we NOT conclude? O A. Both plants and animal cells spend most of their time in interphase; doubling all of the organelles and DNA requires a lot of time. O B. Animal cells spend more of their time in mitosis (dividing the nucleus) than plant cells do. O C. Plant cells spend more time in interphase and telophase than animal cells and animal cells spend more time in prophase, and anaphase than plant cells. O D. Plant cells divide more quickly than animal cells.

Figure 28.11 depicts the eukaryotic cell cycle. Many cell types â€œexitâ€� the cell cycle and donâ€™t divide for prolonged periods, a state termedG0; some, for example neurons, never divide again. a. In what stage of the cell cycle do you suppose a cell might be when it exits the cell cycle and enters G0? b. The cell cycle is controlled by checkpoints, cyclins, and CDKs. Describe how biochemical events involving cyclins and CDKs might control passage of a dividing cell through the cell cycle.
The cell cycle of an average mammalian cell is illustrated below. How long did it take for the above-illustrated mammalian cell to complete one cell cycle?How long did the mitosis/cytokinesis phase (M phase) last? What % of the total cell-cycle timedoes that constitute to? What phase takes the longest time to complete during cell cycle and what % of the total cellcycle time does that constitute to? Explain why you think this might be the longest phase of thecell cycle.How long was the S phase? What is happening in the cell during the S phase?
One approach to studying the regulation of cell cycle progression (particularly in an era when genetic and molecular biology manipulations were less readily accomplished in mammalian cells) was to use treatments that induced cells to fuse and then monitor the behavior of the two nuclei in the resulting cell. The figure below depicts data from one such study. The investigators did preliminary work to produce populations of cells that were synchronized in various stages of the cell cycle (G1, S, or G2 in the examples shown below). They then fused the cells in different combinations and monitored subsequent events in each of the nuclei. For purposes of this question, we will pay particular attention to what occurred in the nucleus that came from the cell in G1. In one experiment (I), cells in the G1 and S phases were fused. That event caused the nucleus from the G1 cell to very quickly enter the S phase (sooner than it would otherwise have done so). In contrast, in a second experiment…

Which of the following statements is FALSE? A. Centrosomes are anchor points for microtubules and are essential to form the mitotic spindle. B. In the eukaryotic cell cycle the cell spends much more time in the interphase than in the mitotic phase. C. In telophase two nuclear envelopes are fully formed and the cell splits in two via cytokinesis. D. The contraction of the kinetochore microtubules leads to the separation of the sister chromatids during anaphase. E. In the prophase chromatin condenses into X-shaped chromosomes.
Looking at the the time intervals in the figure given, compare the time spent in mitosis with the time spent in gap1 in human liver cells. A. less time is spent in G1 than in M B. a little more time is spent in G1 than in M C. The cell spends 10 hours less in G1 than it does in M D. The cell spends 10 hours more in G1 than it does in M
Which of the following statements are correct? Explain your answers. Cells do not pass from G1 into M phase of the cell cycle unless there are sufficient nutrients to complete an entire cell cycle. Apoptosis is mediated by special intracellular proteases, one of which cleaves nuclear lamins. Developing neurons compete for limited amounts of survival factors. Some vertebrate cell-cycle control proteins function when expressed in yeast cells. The enzymatic activity of a CDK protein is determined both by the presence of a bound cyclin and by the phosphorylation state of the CDK.
A student examines a thin section of an onion-root tip and records the number of cells that are in each stage of the cell cycle. She observes 94 cells in interphase, 14 cells in prophase, 3 cells in prometaphase, 3 cells in metaphase, 5 cells in anaphase, and 1 cell in telophase. If the complete cell cycle in an onion-root tip requires 22 hours, what is the average duration of each stage in the cycle? Assume that all cells are in the active cell cycle (not G0).
Passage of cells from G1 through R to S depends on the interaction of various signal molecules, proteins and enzymes which regulate the cell cycle. Imagine I have just induced a mutation in a cell line which prevents the breakdown of the cyclin molecule we discussed. Which of the following events do you predict will happen? circle all that apply Select one or more: a. Uncontrolled cell replication may result b. Retinoblastoma protein will be continuously active c. The cells will be stuck in G1 phase d. The cells will begin to replicate their DNA e. Cyclin dependent kinase (Cdk) will be continuously active

Which stage of the cell cycle is the longest? Why are onion root tips a good choice for viewing cells in different stages of the cell cycle? Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?
Which of the following statements correctly identifies the difference between plant and animal cell division? Select one: a. The cell walls of plants prevent the process of cytokinesis. b. Plants cells lack centrioles, and they form a cell plate during cytokinesis. c. Both plant and animal cells undergo mitosis and cytokinesis, but they lack the interphase. d. Plant cells lack centromeres, and they form a cell wall to produce two daughter cells.
