Different chromatin structures along the spacers flanking active and inactive Xenopus rRNA genes.
The accessibility of DNA in chromatin to psoralen was assayed to compare the chromatin structure of the rRNA coding and spacer regions of the two related frog species Xenopus laevis and Xenopus borealis. Isolated nuclei from tissue culture cells were photoreacted with psoralen, and the extent of cro...
