Hoskins mitosis
DNA replication/mitosis
| Question | Answer |
|---|---|
| Cell division | Also known as Mitosis - making an exact copy of a cell |
| DNA replication | process where DNA's double helix unzips, and two identical new DNA molecules are formed. |
| Chromatin | DNA molecule forms strands of this in the nucleus during Interphase |
| Chromosome | Chromatin winds tightly to form these structures during mitosis. Humans have 23 pairs. |
| Interphase | Stage in cell cycle when DNA replication takes place - most of a cells life is spent in this phase |
| Prophase | Initial phase of mitosis - *Nuclear membrane disappears - *Chromosomes appear |
| Metaphase | 2nd stage of mitosis- *Spindle fibers appear *Chromosomes line up in the middle of the cell 2. |
| Anaphase | 3rd phase of mitosis *Spindle fibers pull chromosomes apart toward the poles - *chromosomes begin to unwind |
| homologous chromosomes | pairs of similar, but not identical, chromosomes visible during the stages of mitosis |
| nuclear membrane | plasma memebrane surrounding the contents of the nucleus during interphase |
| homologous chromosomes | pairs of similar, but not identical, chromosomes visible during the stages of mitosis |
| nuclear membrane | plasma memebrane surrounding the contents of the nucleus during interphase |
| telophase | Last stage of Mitosis- *Nuclear membrane reappears around chromatin -*cytokinesis is completed;two new daughter cells are formed |
| cytokinesis | occurs in telophase - *cytoplasm and organelles are divided to form 2 new daughter cells |
