Allie’s cells lesson 3 science notecards
| Term | Definition |
|---|---|
| Cell cycle | The regular sequence of growth and division that cells undergo. |
| Interphase | The stage of the cell cycle that takes place before cell division occurs |
| Replication | The process by which a cell makes a copy of the DNA in its nucleus |
| Mitosis | The stage of the cell cycle during which the cells nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell |
| Chromosomes | A double rod of condensed chromatin; contains DNA that carries genetic information |
| Cytokinesis | The final stage of the cell cycle, in which the cell’s cytoplasm divides, distributing the organelles into each of the two new cells |
| What takes place during the three stages of the cell cycle? | During Interphase the cell makes a copy of its DNA. During mitosis, one copy of the DNA is distributed into each of the two daughter cells. During cytokinesis, The cytoplasm divides. The organelles are distributed into each of the two new cells. |
| Draw and label the cell cycle | See paper |
| Explain DNA replication and how it accounts for the way it copies itself | DNA replication ensures that each daughter cells will have the genetic information it needs to carry out its activities. |
