1. What phase is the cell shown in? Interphase What are the long and threadlike chromosomes in this stage called? Chromatin What percentage of the cell cycle is spent in interphase? 90%
2. What are the three parts of interphase called? G1 G2 Synthesis What happens to the DNA during the synthesis stage? Duplication
3. Why do we duplicate the DNA during interphase? So that the daughter cells have the same information as the mother cell!
4. What phase is the cell shown in? Prophase The original and duplicate strands of DNA are called sister…. Chromatids What disappears during prophase? Nuclear membrane, nucleolus
5. What are the two organelles (circled in red) that migrated to opposite poles of the cell during prophase called? Centrioles What role do these organelles play in cell division? They form the spindle apparatus
7. What phase is the cell shown in? Metaphase Where are the chromatids located during metaphase? M iddle What’s another name for the center or middle of the cell? Equator
8. What phase is the cell shown in? Anaphase What attaches the chromatids to the spindle fibers? Centromere
9. What phase is the cell shown in? Telophase What reappears in this phase? Nuclear membrane, nucleolus Cell plate
10. How does cytokinesis differ in this cell from the one shown in the previous slide?
11. What do we call the two cells formed from mitosis? Daughter cells
