Question | Answer |
---|---|
interphase | *phase between sell division*phase the cell spends most time in*g1-the cell grows producing organelles ,protein, cytoplasm*s-DNA is replicated*g2-continued growth |
mitosis | cell divion;made up of 4 phases:prophase,metaphase,anaphase,telophase(PMAT) |
prophase | *chromatin condense to form to form chromatids and homologous chromatids pair together to form a chromosome*nucleolus disapears*nuclear membrane disappears*centriolrs begin to move to opposite poles*spindle fibers begin to form between the centrioles |
metaphase | the cromosomes line up at the equator of the cell |
anaphase | *centromeres split*the chromatidsmove to oppisite poles and are called chromosomes again |
telophase | *chromosomes uncoil*nucleos membrane and nucleolus reappear*spindles go away*cytokinesis,division of cytoplasm,begins |
daughter cell | they are identical to the parent cell |
