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. |
