Exploring The Interphase and Four Stages of Division

  INTERPHASE normal functions preparing to divide DNA unravelled, replicated organelles replicated (spare) ATP content increased (needed for cell division) Four stages of division 1 PROPHASE chromosomes condense getting shorter, fatter; centrioles move to opposite ends of the cell forming spindle ; nuclear envelope breaksdown allowing chromosomes to lie free in the cytoplasm 2 META PHASE chromosomes line up in the middle and become attached to the spindle by centromere 3 ANAPHASE centromeres divide separating each chromatids; spindles contract pulling chromatids to opposite poles of the spindle, centromere first chromatids appear shaped
