Chromatin structure and methylation of rat rRNA genes studied by formaldehyde fixation and psoralen cross-linking.
By using formaldehyde cross-linking of histones to DNA and gel retardation assays we show that formaldehyde fixation, similar to previously established psoralen photocross-linking, discriminates between nucleosome- packed (inactive) and nucleosome-free (active) fractions of ribosomal RNA genes. By b...
