How are specific genes or chromosomes targeted for epigenetic changes? 1. transcription factors may bind to a specific gene and recruit proteins such as histone-modifying enzymes and DNA methyltransferase which leads to epigenetic changes. Chromatin remodeling is the dynamic modification of chromatin architecture to allow access of condensed genomic DNA to the regulatory transcription machinery proteins, and thereby control gene expression. Such remodeling is principally carried out by 1) covalent histone modifications by specific enzymes, … See more The transcriptional regulation of the genome is controlled primarily at the preinitiation stage by binding of the core transcriptional machinery proteins (namely, RNA polymerase, transcription factors, and … See more In normal biological processes Chromatin remodeling plays a central role in the regulation of gene expression by providing the … See more • Chen T, Dent SY (February 2014).
