 Living organisms reproduce by two ways: | 1. Asexual reproduction 2. Sexual reproduction |
| Cellular Reproduction involves two important processes: | 1. Growth 2. Cell Division |
| Involves duplication of the cell's DNA and contents in cytoplasm. | Growth |
| Involves the separation of the cell's DNA and content into daughter cells. | Cell Division |
| Eukaryotic chromosomes are composed of: | - Chromotin |
| Chromotin = | DNA+Proteins |
| The process of cellular reproduction involves an ordered series of steps | Cell Cycle |
| A cell spends most of its existence in what phase? | Interphase |
| The ____ is an ordered sequence of events for cell division. | Cell Cycle |
| Cell cycle consists of two stages: | 1. Interphase 2. Mitotic Phase |
| Interphase is the duplication of cell contents. It has 3 steps: | 1. G1 (1st Gap) 2. S (Synthesis) 3. G2 (2nd Gap) |
| G1 (1st gap) in intephase is: | Growth, increase in cytoplasm |
| S (synthesis) in interphase is: | Duplication of chromosomes - DNA replication |
| G2 (2nd gap) in interphase is: | Growth, preparation for division |
| Mitotic phase is division. It consists of two steps: | 1. Mitosis 2. Cytokinesis |
| Mitosis has a series of stages: | 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase and Cytokinesis which often overlaps Telophase. |
