The enhancers and promoters of the Xenopus laevis ribosomal spacer are associated with histones upon active transcription of the ribosomal genes.
The presence of histones on the enhancer-promoter region of the X.laevis ribosomal spacer has been studied in embryos at stage 40, where the ribosomal genes are actively transcribed. Isolated tadpole nuclei were either fixed with formaldehyde or irradiated with UV laser to crosslink histones to DNA....
