The Cell Cycle & Mitosis Ii Crossword Puzzle

QUESTIONS LIST:

• anaphase: during this phase of mitosis, the spindle fibres begin to contract and shorten, which pulls the centromere apart, allowing the sister chromatids to move to opposite poles of the cell.
• telophase: in this final stage of mitosis, one complete set of chromosomes is now at each pole of the cell. the spindle fibres begin to disappear, and a nuclear membrane forms around each set of chromosomes. a nucleolus appears within each nucleus.
• cytokinesis: this is the final stage of the cell cycle when the two nuclei and other cell contents separate into two daughter cells.
• cleavage furrow: during cytokinesis in animal cells, this forms to divide the cell’s cytoplasm and organelles.
• cell plate: during cytokinesis in plant cells, this forms to divide the cell’s cytoplasm and organelles.
• checkpoints: activities within the cell are monitored and controlled at these points in specific stages of the cell cycle.
• damaged: a cell will not divide if at a checkpoint it is detected that the dna is this.
• nutrients: a cell will not divide if at a checkpoint it is detected that there are not enough of these to support cell growth.
• spindle fibres: these tiny, tube-like protein structures that form in prophase attach to the centromeres of a chromosome.
• centromere: this is a constricted region of a chromosome.
• centrioles: these are organelles that “organize” spindle fibres during mitosis.
