8664701418 | Mitosis | Cell division that produces normal cells, produces two identical daughter cells. | 0 | |
8664701420 | Centrioles | In animal cells, they organize microtubules into spindle fibers. These guide chromosomes in mitosis. | 1 | |
8664701421 | IPMAT | Pneumonic device to remember the stages and order of cell division: Interphase, Prophase, Metaphase, Anaphase, and Telophase. | 2 | |
8664701422 | Interphase | 90% of the cell cycle. The cell does its "everyday job": RNA is produced, proteins are synthesized. The cell is preparing for duplication -- it is ready whenever it is triggered. | ![]() | 3 |
8664701423 | G1 Phase | Initiated by a signal to divide. 1st growth period of the cell. Cell does its "everyday job." Cell grows, preparing for division. | 4 | |
8664701424 | S Phase | DNA Synthesis. The cell copies chromosomes. | 5 | |
8664701425 | Chromatin | The DNA-Protein complex formed when DNA molecules wrap around histone proteins. | 6 | |
8664701426 | Chromosomes | A doubled rod of condensed chromatin; contains DNA that carries genetic information. | 7 | |
8664701428 | Centromeres | Area where the chromatids of a chromosome are attached. | 8 | |
8664701429 | Sister Chromatids | Replicated forms of a chromosome joined together by the centromere and eventually separated during mitosis. | 9 | |
8664701430 | Homologous Chromosomes | Chromosomes that have the same sequence of genes, that have the same structure and code for the same gene, but may have different alleles. | 10 | |
8664701431 | G2 Phase | The cell prepares for division. Cell grows even more. Produces more organelles, proteins, and membranes. | 11 | |
8664701432 | Prophase | Chromatin condenses. Centrioles move to opposite poles of cell. Protein fibers cross cell to form mitotic spindle. Nuclear membrane breaks down. | 12 | |
8664701435 | spindle | fanlike microtubule structure that helps separate the chromosomes during mitosis | 13 | |
8664701436 | Metaphase | Chromosomes align along middle of cell, ensuring chromosomes separate properly. | 14 | |
8664701438 | Anaphase | Sister chromatids separate, poles move farther apart. | 15 | |
8664701440 | Telophase | Chromosomes arrive at opposite poles. Spindle fibers disperse. Cytokinesis begins. | 16 | |
8664701446 | Cancer | A collection of related diseases in which cells divide uncontrollably | 17 | |
8664701447 | G1 | Checkpoint where if cell is not ready to divide it may arrest here (G0 phase - nerve and muscle cells remain here, rarely divide after maturing) and never proceed or wait until it is ready. | 18 | |
8664701448 | S | DNA damage checkpoint: DNA recplication halted if genome is damage | 19 | |
8664701449 | cyclin | one family of proteins that regulates the cell cycle in eukaryotic cells | 20 | |
8664701468 | Metastasis | The spread of cancer cells beyond their original site | 21 | |
8664701469 | density-dependent inhibition | crowded cells stop dividing | 22 | |
8664701470 | anchorage dependence | The requirement that to divide, a cell must be attached to a solid surface. | 23 | |
8664701471 | tumor-suppressor genes | a gene whose protein product inhibits cell division, thereby preventing the uncontrolled cell growth that contributes to cancer (ex p53) | 24 | |
8664701472 | Proto-oncogenes | Genes that stimulate mitosis | 25 |

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!
