Regulation of c-fos gene expression in hamster fibroblasts: initiation and elongation of transcription and mRNA degradation.

abstract：:Nucleosomes are the most abundant protein-DNA complexes in eukaryotes that provide compaction of genomic DNA and are implicated in regulation of transcription, DNA replication and repair. The details of DNA positioning on the nucleosome and the DNA conformation can provide key regulatory signals. Hydroxyl-radical foot...
