Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs
RECOGNIZING THE STAGES OF MITOSIS Use the Decision Tree in Figure 8-1 to identify the stages of the cell cycle in Figure 8-2. ACTIVITY 2 no ↓ nucleus visible no Į yes full size cells choose turmella mw another cell interphase chromosomes visible yes ↓ no yes duplicated chromosomes lined up at equator (center of cell) nuclear membrane visible no spindle fibers visible sister chromatids attached together yes yes no no cytokinesis visible later early prophase prophase metaphase anaphase FIGURE 8-1. Mitosis Decision Tree yes daughter cells completely separated no yes mitosis telophase complete
Which of the following events does not normally occur in mitosis? Separation of sister chromatids from each other Formation of synaptonemal complexes Attachment of spindle fibers to centromeres Movement of sister chromatids to opposite poles Alignment of chromosomes along the metaphase plate
Which of the following is NOT correct answer about telophase of mitosis: The mitotic spindle is formed in this phase Two new nuclei form, and two sets of chromosomes Nuclear membrane and nucleoid reappear in this phase The enzyme aminoacyl TRNA synthetase charges the TRNA molecules with the correct amino acids FRNA molecules with the correct amino acids MRNA molecules with the correct amino acids
Review the events associated with each stage of mitosis in addition to the preparatory stage, interphase. List these events in table. Some events and structures occur only in plant cells and some occur only in animal cells. Mark these events in your list with an asterisk. This list can serve as an excellent study guide, so be as complete as possible. Interphase Prophase Prometaphase Metaphase Anaphase Telophase
Re-write the following statement to make it true: "Mitotic CDK is absent when the cell is in interphase and is present only during mitosis."
