Mitosis
Biology
Question | Answer |
---|---|
How many cells are present at the beginning of mitosis? | One |
How many cells are present at the end of mitosis? | Two |
Which phase of mitosis do you see the spindle fibers forming? | Prophase (late) |
At what point during mitosis has the nuclear membrane reformed? | During telophase |
What phase of mitosis do the replicated chromosomes separate? | Anaphase |
What phase do you see that the spindle fibers have disappeared? | Telophase |
What is dividing during cytokinesis? | Cytoplasm of the cell and its non-nuclear contents. |
What holds sister chromatids together at center? | Centromere |
Prophase characteristics | Replicated chromosomes become visible, spindle fibers form and membrane starts to disintegrate. |
Metaphase characteristics | Replicated chromosomes line up in center of cell and spindle fibers attach at their centers. |
Anaphase characteristics | Spindle fibers separate(sister chromatid pairs) into single chromosomes and move to opposite sides of cell. |
Telophase characteristics | Single chromosomes in two "piles" that become two new nuclei and nuclear membrane begins to form. |
Cytokinesis characteristics | Original cell pinches in two and make two new cells. |
