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.
Assign a function(s) to the following cellular structures: a. plasma membrane b. mitochondrion c. nucleus d. ribosome
Which one of the following represents interphase? A. G1 + G2 + S B. S + M + C C. prophase + metaphase + anaphase + telophase D. cytokinesis + mitosis E. G1 + G2
What from mitosis is triggered by mitotic CDK inactivationmainly brought about by mitotic cyclin degradation.
What is the order in which the following events occur during cell division: A. anaphase B. metaphase C. prometaphaseD. telophase E. lunar phaseF. mitosis G. prophaseWhere does cytokinesis fit in?
During which of the following mitotic stages to microtubules shrink to pull chromosomes to the MTOC? a. Prophase b. Metaphase c. Anaphase d. Telophase e. Cytokinesis
Even though cytokinesis is included with Mitosis, we generally consider it to be its own phase. Why? by the time cytokinesis occurs, the cell has already split by the time cytokinesis occurs, the cytoplasm has already split by the time cytokinesis occurs, the nucleus has already split by the time cytokinesis occurs, the cell has copied all of its chromosomes
Centrosomes move to opposite ends of the cell in what phase of mitosis? a. Metaphase b. Anaphase c. Telophase d. Interphase e. Prophase
Identify the phase(s) from the image above that best illustrates each of the following stages of mitosis AND include your explanation of why. a. Interphaseb. Prophasec. Metaphased. Anaphasee. Telophase/Cytokinesis
Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. Draw a 2n=4 cell at G1 of interphase. Draw the same cell at the start of prophase. Draw the same cell at metaphase. Draw the cell(s) that result at the end of cytokinesis.
