From: Dramatic nucleolar dispersion in the salivary gland of Schwenkfeldina sp. (Diptera: Sciaridae)
(a–c) Localisation of the rDNA in Schwenkfeldina sp. polytene chromosomes from Malpighian Tubules showing RNA probe signal (a), its corresponding DAPI staining image (b) and the merged signals (c). Dispersion of the rDNA in these nuclei is usually lower than that observed in posterior cells of the salivary gland. Bar = 25 µm.
