- Match the stage of mitosis with the correct description. a.Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart. b.The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage. c.The chromosomes that were pulled apart reach therir respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides. d.Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The chromosomes begin to condense into individual structures. e.Centrosomes move to the opposite ends of the cell and establish two spindle poles.The nuclear envelope is completely degraded by the end of this stage. The chromosomes are completely consensed by the end of this stage. f.Not actually part of mitosis; this stage is the part of the cell cycle that is not the mitotic phase.
