a critical role in transcriptional regulation. Chromatin can inhibit access of transcription factors to the DNA and can thereby repress gene expression. In eukaryotic organisms, with their very large number of genes (approximately 40 310 in mammals), this means that the ground state of gene expression is for genes to be turned off. Activation
