5459445476 | G1 Phase | Primary growth phase of the cell | 0 | |
5459445477 | S Phase | Phase where genome is replicated | 1 | |
5459445478 | G2 Phase | Preparation made for separation of genomes; organelles replicate, chromosomes condense, microtubules assemble | 2 | |
5459445479 | Interphase | Collective name for G1, S, and G2 Phases | 3 | |
5459445480 | Anaphase (A) | Phase where microtubules pull sister chromatids apart | 4 | |
5459445481 | Cytokinesis (C) | Cytoplasm divides; forms 2 daughter cells | 5 | |
5459445482 | Sister Chromatids | The two identical copies formed by the replication of a single chromosome, joined by centromere | 6 | |
5459445483 | Centromere | Links sister chromatids | 7 | |
5459445484 | Kinetochore | Protein disk bound to specific DNA sequence at centromere | 8 | |
5459445485 | Mitotic Phase | Includes both mitosis and cytokinesis | 9 | |
5459445486 | Mitotic Spindle | Consists of fibers made of microtubules and associated proteins | 10 | |
5459445487 | Centrosome | Subcellular region containing material that functions through the cell cycle to organize the cell's microtubules | 11 | |
5459445488 | Prophase | Chromatin fibers condense into chromosomes, mitotic spindle begins to form, centromeres move away from each other | ![]() | 12 |
5459445489 | Prometaphase | Nuclear envelope fragments, Each of the two chromatids now has kinetochore, some microtubules attach to kinetochores | ![]() | 13 |
5459445490 | Metaphase | Centrosomes at opposite poles of the cell, Chromosomes convene at metaphase plate | ![]() | 14 |
5459445491 | Anaphase | Beginning when sister chromatids separate from each other and ending when a complete set of daughter chromosomes have arrived at each of the two poles of the cell | ![]() | 15 |
5459445492 | Telophase | Two daughter nuclei form in the cell, nuclear envelope forms | ![]() | 16 |
5459445493 | G1 Checkpoint | Most important checkpoint; if cell receives go-ahead signal, the the cell continues with the cell; in the absence of the go-ahead signal, cell exits the cell cycle and enter the G0 phase | 17 | |
5459445494 | M Checkpoint | Cell in mitosis receives a stop signal when any of its chromosomes are not attached to spindle fibers | 18 |

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
