Lesson 3
| Term | Definition |
|---|---|
| Cell cycle | The regular sequence of growth and division that cells undergo |
| Interface | 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 cell’s 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? | 1) the cell grows and makes a copy of its DNA 2) one copy of the DNA is distributed into each of the two daughter cells 3) the cell divides |
| Draw and label the cell cycle | See notes |
| Explain DNA replication and how it accounts for the way it copies itself | because of the way in which the nitrogen bases pair with one another, the order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule |
