Bio Cell Cycle
Cell Cycle
| Term | Definition |
|---|---|
| Cell Cycle | events in the life of a cell that results in growth, duplication of DNA in order to produce new cells |
| G1 | phase of cell growth prior to cell division |
| S | phase for DNA synthesis |
| G2 | cell goes through growth phase; DNA copy is checked for mistakes more cytoplasm and organelles are made |
| G0 | carries out normal functions but does not divide; these cells remove themselves from the cell cycle |
| Interphase | includes G phases and S phase |
| Mitosis | phase where cell divides its identical copied DNA to make 2 identical diploid cells; includes prophase, metaphase, anaphase, and telophase |
| Prophase | replicated chromosomes condense; nuclear envelope breaks down; mitotic spindles begin to form |
| Metaphase | microtubules attach to chromosomes aligning them on equator |
| Anaphase | sister chromatids are pulled apart by spindle microtubules; 2 sets of daughter chromosomes created |
| Telophase | daughter chromosomes reach spindle poles; nuclear envelope reforms around the two nuclei |
| Cytokinesis | two new daughter cells formed; occurs after mitosis |
| Diploid | cell with 2 sets of chromosomes (1 set from each parent); not found in gametes; end product of mitosis |
| Somatic Cells | all cells except sex cells (also known as gamete like sperm and egg); diploid cells; result of mitosis |
