Fig. 8. Morphological changes of pre-meiotic germ cell nuclei induced by
hydroxyurea. Images are DAPI-stained nuclei in untreated (HU) gonads
and in those exposed to hydroxyurea (+HU). Upon HU treatment, pre-meiotic
nuclei in the wild-type N2 gonad were substantially enlarged and reduced in
number, but those in the wrn-1(RNAi) gonad were much smaller. Scale
bar: 50 µm.
