Fibers Chromosomes Nuclear Spindle Draw Annotate Describe Occurs

Front Draw, annotate and describe what occurs during prophase.
Back Prophase:
  • Chromatin fibers begin to coil & condense forming chromosomes (visible if stained)
  • Nucleolus disappears, nuclear membrane starts breaking down
  • Protein microtubules form spindle fibers
  • If cell has centrioles, they migrate to opposite poles of cells
  • Spindle fibers attach to specific areas on centromeres, start moving chromosomes to center
  • By the end, nuclear envelope has disappeard
