Transcription sites form a distinct compartment in the nucleus of P. falciparum. Immunofluorescence assay for nascent RNAs of ring stage parasites labeled with BrUTP (BrRNA, green) and the compartments of acetylated H4 (H4ac, active chromatin); a proposed histone marker of nascent transcription (H3K79me3; PfSir2A (silencing compartment); and Nop1 (nucleolar compartment). DNA was labeled by DAPI, in blue. Bars, 1 mm.
