Question | Answer |
Interphase | Chromosomes are duplicated and prepares for mitosis or cell division |
Prophase | Nucleus and nuclear membrane disintegrate or disappears. Centrioles move to opposite ends of the cell. Spindle fibers begins to stretch across the cell. |
Metaphase | Chromatids line up across the middle of the cell. the centromere of each pair usually attach with two spindle fibers |
Anaphase | Chromatids separate and begin to move to opposite ends of the cell. Each centromere divides and spindle fibers shorten |
Telophase | Two new nuclei form and spindle fibers disappear. Mitosis is over. |
Cytokineisis | Cell membrane moves inward to create two daughter cells. Each new cell has its own nucleus with identical chromosomes. |
Cell Cycle | Series of events from one cell division to the next |
Chromosome | Structure in the nucleus that contains hereditary material |
Undduplicated chromosome | One strand of DNA |
Duplicated Chromosome | Two strands of identical DNA called a chromatid, and is held together with a centromere |
Asexual Reproduction | A type of reproduction when an organism is created from one parent organism. The new organism and the parent are identical to each other. Their hereditary material is identical to each other. |
Fission | Form of asexual reproduction in which two new cell s are produced with the genetic material identical to each other and the original cell. |
Regeneration | Form of asexual reproduction in which an organism regrows lost body parts. |
Budding | Form of asexual reproduction in which a new organism forms on the side of the parent organism |
Cloning | An individual that is genetically identical to one of its parents. |
Meiosis I | The nucleus divides and produces two new cell with one duplicated chromosome each. |
Meiosis II | The nuclei divide and the chromatids separate, producing haploid sex cells with half the number of chromosomes of the original nucleus. |
Meiosis | A process that produces haploid sex cells and ensures that offspring have the same number of chromosomes as its parent when they join. |
Mitosis | A process in which the nucleus divides to form two nuclei which is identical to each other. |
