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. |
