Which stage of Mitosis is characterized by the nuclear membrane disappearing, the chromosomes becoming visible, and the centrioles beginning to move to opposite ends of the cell?

• Telophase

• Metaphase

• Prophase

• Anaphase

Which stage of Mitosis is characterized by the spindle fibers (created by the centrioles) attaching to the chromosomes and lining them up in the middle of the cell?

• Telophase

• Metaphase

• Prophase

• Anaphase

Which stage of Mitosis is characterized by the spindle fibers pulling apart the sister chromatids of the chromosomes and dragging them to opposite sides of the cell?

• Telophase

• Metaphase

• Prophase

• Anaphase

Which stage of Mitosis is characterized by nuclear membranes reforming around the 2 groups of chromosomes, the chromosomes going back into chromatin form, the spindle fibers breaking down, and also has cytokinesis occurring at the same time?

• Telophase

• Metaphase

• Prophase

• Anaphase
