The Cell Cycle and Mitosis
| Question | Answer |
|---|---|
| What are the 3 main phases of the cell cycle? | Interphase, Mitosis, Cytokinesis |
| What are the 3 parts of Interphase? | G₁ phase, S phase(DNA replication), G₂ phase |
| What are the phases of Mitosis? | Prophase, Metaphase, Anaphase, Telophase |
| This part of Interphase includes the cell grows adding cytoplasm and organelles. In animal cells, centrioles replicate. | G₁ phase |
| This part of Interphase includes DNA is replicated making an exact copy of itself | S |
| This part of Interphase includes organelles such as mitochondria and microtubules needed for mitosis are made. | G₂ phase |
| Mitosis is also known as: | nuclear division |
| In mitosis (prophase) the nuclear membrane and nucleolus _____________ | disappear |
| In mitosis (prophase) Chromatin condenses and forms __________ ____________. | doubled chromosomes |
| In mitosis (prophase) ________________ split and go to opposite poles. | centrioles |
| In mitosis (prophase) _____________ apparatus appears | spindle |
| In mitosis (metaphase) chromosomes attach to the spindle at the ___________ with _______________ | centromere, kinetochore |
| In mitosis (metaphase) chromosomes line up along the ____________ in the middle of the cell. | equator |
| In mitosis (anaphase) sister chromatids are __________ __________ | pulled apart |
| In mitosis (anaphase) single chromosomes now exist at the __________ | poles |
| In mitosis telophase is the reverse of ______________ | prophase |
| In mitosis (telophase) nuclear membrane and nucleolus _____________ | reappear |
| In mitosis (telophase) chromosomes uncoil to ________________ | chromatin |
| spindle apparatus _______________ | disappears |
| Cytokinesis in defined as: | division of the cytoplasm |
| cytokinesis occurs near the end of _____________ | telophase |
| During cytokinesis, in plants a cell plate forms which eventually divides the two new __________ _________ | daughter cells |
| During cytokinesis, in animals a ________ ________ pinches the cell membrane inward until it divides the two new daughter cells | cleavage furrow |
