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.
Mitosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of mitosis. Make sure to draw the alleles for genes A and B on the chromatids in every stage. For mitosis, remember that many events are going on in the cell that are relevant besides just the movement of chromosomes, so please fill in the cell with pertinent structures such as centrioles and spindles.
D. centromere QUESTION 8 Match the stages of mitotic cell division to the descriptions of those stages. v chromosomes attach to spindle fibers across the middle of the cell chromosomes are not yet duplicated so chromosomes only look like a line, only one pair of centrioles in cell A. Telophase cell membrane is pinching in forming a peanut-shaped cell, daughter v chromosomes reach the poles and new nuclear membranes are forming around them B. Late Interphase C. Early Interphase the nuclear membrane is breaking down, chromosomes are |condensing, centrioles are building microtubule "highways" (spindle fibers) D. Metaphase E. Anaphase chromosomes are duplicated so chromosomes look like an "X", two pairs of centrioles and double the amount of organelles fill the cell F. Prophase v cell is dividing into two identical cells G. Cytokinesis daughter chromosomes are beginning their migration to the poles on spindle fibers QUESTION 9 How do the two cells formed by a mitotic cell division compare…
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. You can draw this out on paper

Mitosis must be carefully regulated to ensure the normal distribution of chromosomes to the daughter cells. A ring-shaped protein molecule known as cohesin attaches to the centromere of a chromosome and holds sister chromatids together to prevent their premature separation. Enzymes detach cohesin molecules from the centromere immediately before the sister chromatids segregate. -based on Nature, 2006 In which of the cells labelled in the diagram above are enzymes most likely acting to detach cohesin molecules from the centromere?
