Evidence for Endoreduplication: Germ Cell DNA Levels Prior to Chromatin Diminution in Mesocyclops Edax

Rasch, Ellen M., Wyngaard, G. A. 01 June 2001 (has links)
We studied the functional significance of marked differences in the DNA content of somatic cells and germ line nuclei by static Feulgen-DNA cytophotometry for several species of microcrustaceans that exhibit chromatin diminution during very early stages of embryogenesis. Mature females and males showed many gonadal nuclei with elevated amounts of DNA that persist until dispersal of this "extra" DNA throughout the cytoplasm as fragments and coalescing droplets of chromatin during anaphase of the diminution division.
