Bio, Mitosis
Mitosis and the Cell Cycle
| Question | Answer |
|---|---|
| Cell Cycle Order | Interphase Prophase Metaphase Anaphase Telophase Cytokinesis |
| Cancer | Loss of ability to control the cell cycle. Continuous mitosis leads to tumors. |
| External Regulatory Factors | Outside signals that regulate the cell signal. |
| Internal Regulatory Factors | Allows cell cycle to proceed only when previous steps are finished. |
| Cyclins | Proteins that regulate steps in a cell cycle. |
| Interphase | Spindle begins to form |
| Cytokinesis | Two cells are identically split. |
| Telophase | Chromosomes at either ends gather and begin to unwind |
| Anaphase | Sister chromatids seperate and are pulled toward opposite "poles". |
| Metaphase | Spindle completely formed |
| Prophase | Spindle begins to form. |
| M-Phase | Made up of cytokinesis and mitosis. |
| Interphase | G1, G2, S-phase together in the period when the cell is not actively dividing. |
| Preperation for Mitosis | G2 phase, second growth phase |
| DNA replication | S-Phase DNA cell is duplicated. |
| G1 Phase | First Growth when cells perform their cells every day activities such as growing and making organelles. |
| Cell Division | The process by which a cell divides into two new daughter cells. |
| Chromatids | Consists of two identical sister chromatids. |
| Centromeres | Point in the center of a chromatid. |
| Cell Cycle | Series of events that cells go through as they grow and divide. |
| Centrioles | Two tiny structures located in the cytoplasm near the nuclear envelope. |
