Lesson 3
| Question | Answer |
|---|---|
| Cell cycle | Sequence of growth and division that cells undergo |
| Interphase | Cell cycle that takes place before cell division |
| Replication | Cell makes a copy of the DNA in its nucleus |
| Mitosis | Nuclei and one copy of the DNA is distributed into each daughter cell |
| Chromosome | A doubled rod of condensed chromatin contains DNA that carries genetic information |
| Cytokinesis | The final stage of the cell cycle, in which the cell cytoplasm divides, distributing the organelles into each of the two new cells |
| Three stages of the cell cycle | Interphase (cell growth & DNA prep), Mitosis (nucleus divides), and Cytokinesis (cytoplasm divides) |
| Labeling the cell cycle | Interphase (G1, S, G2) for growth and DNA replication, and the M Phase (Mitosis & Cytokinesis) for cell division |
| DNA replication and how it accounts for the way it copies itself | through a semi-conservative process where the double helix unwinds, each old strand acts as a template, and enzymes (like DNA Polymerase) build new complementary strands, resulting in two identical DNA molecules, each with one original and one new strand, |
