Mitosis overview Flashcards
Bio 9
Rapid cell growth to mature size
Interphase G1
Centrioles double
Interphase G1
DNA is replicated
Interphase S
Additional cell growth
Interphase G2
Proteins and enzymes needed are produced
Interphase G2
Chromatin condenses to chromosomes
Prophase
Nuclear membrane and nucleolus dissolve
Prophase
Two pairs of centrioles migrate to opposite poles of the cell
Prophase
Spindle fibers radiate from centrioles in attached to chromosomes
Prophase
Metaphase plate
Metaphase
Spindle fibers move the chromosomes to the middle of the cell
Metaphase
Chromatids separate at centromere and get pulled to opposite poles by the spindle fibers
Anaphase
Chromatids are considered chromosomes
Anaphase
Chromosomes reach opposite poles
Anaphase
Cell begins to pinch off
Telophase
Chromosomes condense (back to chromatin)
Telophase
Spindle fibers breakdown
Telophase
Nuclear membrane and nucleolus reform
Telophase
Cleavage furrow form and dividing cell
Cytokinesis (Animal)
Equal division of cytoplasm
Cytokinesis Animal / Plant
Cell plate forms
Cytokinesis (plant)
Vessels from Golgi complex fused at midline of dividing cell
Cytokinesis (plant)
Two new daughter cells (clones)
Overall
Half cytoplasm, half size full complement of chromosomes
