Cell division
| Term | Definition |
|---|---|
| CENTROMERE | The region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division. |
| CYCLIN | Protein that regulates the cell cycle, then acts as a signal letting the cell know when to pass to the next cell cycle phase. |
| INTERPHASE | Is the preparation period between cell divisions containing (G₁, S, and G₂ phases). |
| ANAPHASE | A process that separates (divides) the duplicated DNA of a parent cell. |
| CELL CYCLE | The series of events that take place in a cell leading to duplication of its DNA and division of the cytoplasm. |
| CELL DIVISION | Is the process by which a single "parent cell" divides into two or more daughter cells. |
| METAPHASE | Stage where chromosomes "meet in the middle" before being separated into chromatids, and placed into the daughter cells. |
| TELOPHASE | Begins once the replicated, paired chromosomes have been separated & pulled to opposite sides of the cell (just before it splits into 2 new cells). |
| CENTRIOLE | Is near the nucleus in animal cells, occurring in "PAIRS" and involved in the "development of spindle fibers" in cell division. |
| SPINDLE | Composed of microtubules which segregates chromosomes into the daughter cells during mitosis. |
| CYTOKINESIS | The cytoplasmic division of a cell at the end of mitosis. |
| CANCER | Essentially a disease of mitosis - the normal 'checkpoints' regulating mitosis are ignored by the cancer cells. They divide faster than other cells. |
| PROPHASE | Is the 1st stage of cell division where the chromosomes become visible as "paired" chromatids and the nuclear envelope disappears. |
| CHROMATID | Is ONE the two threadlike strands into which a chromosome divides longitudinally during cell division. |
| MITOSIS | Is a part of the cell cycle when replicated chromosomes are separated into two new nuclei. ( AKA: Division of the cell's nucleus). |
