Localization and stability of 5S rRNA nucleosomes. Δls profiles (black line) of 869-bp long 5S rDNA sequence from Xenopus borealis. Nucleosomal positions mapped with micrococcal nuclease [35] (black dots in the center of 146-bp long horizontal bars) and mapped according to minimal Δls values (blue dots in the center of 146-bp long horizontal bars) are reported with specific abscissa and ordinate values marked in blue and black digits respectively. The arrow marks the position of the transcription start site.
