| p arm of a chromosome | All human chromosomes have 2 arms -- a short arm and a long armThe short arm of a chromosome.--ymbol "q" was chosen for the long arm |
| q arm of a chromosome | All human chromosomes have 2 arms -- a short arm and a long arm--q arm is long arm |
| Importance of Mitosis | a. Cellular replacement b. Tissue Repair c. Development d. Tumor growth |
| Mitosis | Somatic Cell Nuclear Division |
| Two important processes to maintain constant number of chromosomes.(both done by mitosis)What are they? | Duplication of chromosomes--- Distribution of duplicated chromosomes into two daughter cells |
| Cytokinesis - | division of the cell |
| Animal cell Cytokinesis - | - cytokinesis occurs by constriction of actin fibers |
| Plant cell Cytokinesis | - cytokinesis occurs by synthesis of cell plate. |
| cell cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. |
| Body (somatic) cells divide in 3 stages: | DNA replication duplicates genetic material exactly Mitosis divides genetic material equally Cytokinesis divides cytoplasm and organelles into 2 daughter cells |
