Mitosis
| Question | Answer |
|---|---|
| What is Mitosis? | cell division |
| What are the four stages in Mitosis? | Prophase, Metaphase, Anaphase, and Telophase |
| The longest cell phase. | Interphase |
| How many parts are in Interphase? | three (G1/S/G2) |
| What happens in Prophase? | the nuclear envelope breaks down and strands of chromatin form into chromosomes. |
| What happens in Metaphase? | the duplicated chromosomes line up along the equatorial plate of the spindle. |
| What happens in Anaphase? | the daughter chromosomes move away from each other to opposite ends of the cell. |
| What happens in Telophase? | the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes. |
| How many cell divisions are in Mitosis? | One |
| What kind of cell does mitosis start with? | Parent cell |
| Cytokinesis | The final phase of the cell cycle. The cell splits into two new daughter cells |
| Why do cells divide? | Grow, repair, reproduce |
| What happens during Mitosis? | One diploid cell divides into 2 diploid cells that are identical daughter cells |
| somatic cell | All human body cells |
| Sister chromatids | Condensed forms of chromatin joined by the centromere. Form a chormosome pair.. |
| Centromere | area connecting sister chromatids |
| Spindle fibers | Microtubules that extend form the centrioles. Attach to the centromere. |
| Nucleus | Controls all cell functions |
| DNA | The blueprints of the cell that provide all cell instructions. |
| Diploid | Having two sets of chromosomes |
| Daughter cells | The result of cell division and cytokinesis |
