WebMar 13, 2024 · Abstract. The nucleosome serves as a general gene repressor, preventing all initiation of transcription except that which is brought about by specific positive regulatory mechanisms. The positive mechanisms begin with chromatin-remodeling by complexes that slide, disrupt, or otherwise alter the structure and organization of nucleosomes. WebAug 4, 1999 · Two highly conserved mechanisms for altering chromosome structure have been identified: 1) post-translational modification of histones and 2) adenosine triphosphate (ATP)-dependent chromosome remodeling.
