DNaseI-hypersensitive sites at promoter-like sequences in the spacer of Xenopus laevis and Xenopus borealis ribosomal DNA.
We have detected a DNAseI hypersensitive site in the ribosomal DNA spacer of Xenopus laevis and Xenopus borealis. The site is present in blood and embryonic nuclei of each species. In interspecies hybrids, however, the site is absent in unexpressed borealis rDNA, but is present normally in expressed...
