188 Age-related molecular variability in Caenorhabditis elegans, T. R. Golden et al. Supplemental Table I: predicted nuclear genome copy number in young adult N2 hermaphrodites Table S1 Predicted nuclear genome copy number in young adult N2 hermaphrodites. Movie S1 DAPI staining reveals masses of DNA in the region of the uterus in aged worms. These masses become apparent in middle age, and by 14 days of age, can fill much of the internal space of the worm. In this movie clip, the extent of the DAPI- stained masses in a characteristic 14-day-old wild-type nematode is visualized in three dimensions. Serial optical sections were collected at 63x magnification (see methods). The left panel shows a reconstruction of the worm in three dimensions, while in the right panel the optical sections are displayed in succession as the focal plane moves through the worm.
