Localization of ribosomal cistrons at the ultrastructural level by in situ hybridization technique.
In situ hybridization with 3H 28 S ribosomal RNA at the ultrastructural level shows labelling exclusively over the nucleolus and specifically over the dense nucleolar component (DNC). These findings clearly reveal that the ribosomal cistrons are located in the DNC of the nucleolus.
