Daughter cells produced by mitosis have cytoplasmic content (ie, organelles, cytoplasm, number of mitochondria, etc.) that is identical Chromosomes condense during cytokinesis Homologous chromosomes on separate kinetochores line up together at the metaphase plate Daughter cells obtain a copy of each chromatid from their parent cell During prophase, the mitotic spindle developsRe-write the following statement to make it true: "Mitotic CDK is absent when the cell is in interphase and is present only during mitosis."Mitosis In this worksheet, you will review the steps of mitosis. You will also view an onion root tip and calculate the percentage of cells at each of the stages of cell division. Stages of Mitosis Answer the following questions: 1.
