Nuclei at different stages
1. most vesicular nucleus, at interphase 2. Undergoing APOPTOSISnotice blebbing 3. Intermediate condensed nucleus 4. Less condensed nucleus 5. Anaphase 6. MOST CONDENSED
Condensed/Hyperchromatic Nuclei: heterochromatin predominates low metabolic rate, low activity, http://studydroid.com/printerFriendlyViewPack.php?packId=62003 http://www.wadsworth.org/chemheme/heme/microscope/lymphocytes.htm Vesicular Nuclei: euchromatin predominates; indicates high metabolic rate/active cell [DNA is extended = ready to be read] [purple areas = ribo of rER] http://www.vetmed.vt.edu/education/curriculum/vm8304/lab_companion/histo-path/vm8054/labs/Lab3/Examples/exvesnuc.htm
