Objective: To review the phases of mitosis with the understanding that in a real tissue or a non-synchronized cell culture, different mitotic phases and cells in interphase will be observed at a certain time. Interphase is the period between mitotic events; all other phases are part of mitosis and their individual probabilities add up to the total probability of seeing cells undergoing mitosis. Pay attention to the individual probabilities for cells in each phase of the cell cycle. Problem N° 10 For a certain type of animal tissue, the probability of a randomly selected cell being in a particular stage of the interphase/mitosis cycle is given by the following table: Stage Probability Interphase 0.5 Prophase 0.1 Metaphase 0.05 Anaphase 0.2 Telophase 0.15 Suppose you examine 100 cells at random from this tissue. A) How many cells do you expect to see in metaphase? _____ cells B) You have selected a high magnification (2000 X) in your…

Figure 6.4 Which of the following is the correct order of events in mitosis? a. Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the initotic spindle. The nucleus re-forms and the cell divides. The sister chromatids separate. b. The kinetochore becomes attached to the mitotic spindle. The sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus re-forms and the cell divides. c. The kinetochore becomes attached to metaphase plate. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus re-forms and the cell divides. d. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. The kinetochore breaks apart and the sister chromatids separate. The nucleus re-forms and the cell divides.

Chromosomes are separated replicated during interphase and become separated replicated during mitosis.

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.
