AP Biology: Cell Cycle Flashcards
Terms : Hide Images [1]
| 6733544149 | G1 Phase | Primary growth phase of the cell |  | 0 |
| 6733544150 | S Phase | Phase where genome is replicated | | 1 |
| 6733544151 | G2 Phase | Preparation made for separation of genomes; organelles replicate, chromosomes condense, microtubules assemble | | 2 |
| 6733544152 | Interphase | Collective name for G1, S, and G2 Phases | | 3 |
| 6733544153 | Mitosis (M) | Phase where microtubules pull sister chromatids apart |  | 4 |
| 6733544154 | Cytokinesis (C) | Cytoplasm divides; forms 2 daughter cells |  | 5 |
| 6733544155 | Sister Chromatids | The two identical copies formed by the replication of a single chromosome, joined by centromere |  | 6 |
| 6733544156 | Centromere | Links sister chromatids |  | 7 |
| 6733544157 | Kinetochore | Protein disk bound to specific DNA sequence at centromere |  | 8 |
| 6733544158 | Mitotic Phase | Includes both mitosis and cytokinesis | 9 | |
| 6733544159 | Mitotic Spindle | Consists of fibers made of microtubules and associated proteins |  | 10 |
| 6733544160 | Centrosome | Subcellular region containing material that functions through the cell cycle to organize the cell's microtubules | 11 | |
| 6733544161 | Prophase | Chromatin fibers condense into chromosomes, mitotic spindle begins to form, centromeres move away from each other |  | 12 |
| 6733544162 | Prometaphase | Nuclear envelope fragments, Each of the two chromatids now has kinetochore, some microtubules attach to kinetochores |  | 13 |
| 6733544163 | Metaphase | Centrosomes at opposite poles of the cell, Chromosomes convene at metaphase plate |  | 14 |
| 6733544164 | 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 |
| 6733544165 | Telophase | Two daughter nuclei form in the cell, nuclear envelope forms |  | 16 |
| 6733544166 | 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 |
| 6733544167 | M Checkpoint | Cell in mitosis receives a stop signal when any of its chromosomes are not attached to spindle fibers |  | 18 |
