Pericentromere-Repeat RNAs Localized by RNA-FISH during Interphase.
The probe specifically detects forward transcripts (CEN-F, red). RNase A treatment prior to in-situ hybridization eliminates the FISH signals, indicating that the method predominantly detects RNA (bottom nuclei). DNA was DAPI-counterstained (gray). The size bar corresponds to 5 μm.
