1.6 - Cell division - Key terms
Cards in this deck (15)
- 1Cell cycleThe life cycle of the cell, includes interphase, the four phases of mitosis, and cytokinesis.
- 2InterphaseThe period of the cell cycle between cell division. Organelles replicate and DNA synthesis happens.
- 3ProphaseThe first phase of mitosis. Chromosomes become visible (DNA coils up) and the centrioles separate to opposite sides of the cell (in animals).
- 4MetaphaseThe second phase of mitosis, the chromosomes line up on the spindle, across the center of the cell.
- 5AnaphaseThe third phase of mitosis, centromeres split, the spindle fibres shorten and chromosomes separate.
- 6TelophaseThe the final stage of mitosis, a nuclear membrane forms around each set of new chromosomes.
- 7CytokinesisThe final stage of the mitosis, in which the cell's cytoplasm divides into two new cells.
- 8MitosisCell division in which the nucleus divides into two nuclei containing the same number of chromosomes.
- 9Mitotic indexThe number of cells within a microscopic field that are undergoing mitosis; a high mitotic index is usually a more virulent malignancy.
- 10MutagensA chemical or physical agent that interacts with DNA and causes a mutation.
- 11OncogenesA gene whose activity is associated with the conversion of normal cells to cancer cells.
- 12MetastasisThe spread of cancer from its primary site to other places in the body.
- 13Prognostic toolA method of predicting a future event, e.g. response of cancer cells to treatment.
- 14Primary tumorThe original site of a tumor, where the tumor originated.
- 15CyclinsA group of proteins whose function is to regulate the progression of a cell through the cell cycle.
