Terms : Hide Images [1]
| 4938214667 | G1 Phase | Primary growth phase of the cell | 0 | |
| 4938214668 | S Phase | Phase where genome is replicated | 1 | |
| 4938214669 | G2 Phase | Preparation made for separation of genomes; organelles replicate, chromosomes condense, microtubules assemble | 2 | |
| 4938214670 | Interphase | Collective name for G1, S, and G2 Phases | 3 | |
| 4938214671 | Mitosis (M) | Phase where microtubules pull sister chromatids apart | 4 | |
| 4938214672 | Cytokinesis (C) | Cytoplasm divides; forms 2 daughter cells | 5 | |
| 4938214673 | Sister Chromatids | The two identical copies formed by the replication of a single chromosome, joined by centromere | 6 | |
| 4938214674 | Centromere | Links sister chromatids | 7 | |
| 4938214675 | Kinetochore | Protein disk bound to specific DNA sequence at centromere | 8 | |
| 4938214676 | Mitotic Phase | Includes both mitosis and cytokinesis | 9 | |
| 4938214677 | Mitotic Spindle | Consists of fibers made of microtubules and associated proteins | 10 | |
| 4938214678 | Centrosome | Subcellular region containing material that functions through the cell cycle to organize the cell's microtubules | 11 | |
| 4938214679 | Prophase | Chromatin fibers condense into chromosomes, mitotic spindle begins to form, centromeres move away from each other |  | 12 |
| 4938214680 | Prometaphase | Nuclear envelope fragments, Each of the two chromatids now has kinetochore, some microtubules attach to kinetochores |  | 13 |
| 4938214681 | Metaphase | Centrosomes at opposite poles of the cell, Chromosomes convene at metaphase plate |  | 14 |
| 4938214682 | 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 |
| 4938214683 | Telophase | Two daughter nuclei form in the cell, nuclear envelope forms |  | 16 |
| 4938214684 | 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 | |
| 4938214685 | M Checkpoint | Cell in mitosis receives a stop signal when any of its chromosomes are not attached to spindle fibers | 18 |
