WebbDuring prophase, chromatin (tangled-up DNA) in the nucleus condense into chromosomes (bunched-up DNA). Pairs of centrioles move to opposite sides of the nucleus. Spindle fibers begin to form a bridge between the ends of the cell.. Prometaphase. During prometaphase, the nuclear envelope around the chromosomes breaks down. WebbIn higher eukaryotes the end of prophase corresponds to the breakdown of the nuclear envelope.As discussed in Chapter 8, however, nuclear envelope breakdown is not a universal feature of mitosis.In particular, yeasts and …
