Gene repression is crucial to the maintenance of differentiated cell types in multicellular organisms, whereas aberrant silencing can lead to disease. The organization of DNA into chromatin and heterochromatin is implicated in gene silencing. In chromatin, DNA wraps around histones, creating nucleosomes. Further condensation of chromatin, associated with(More)
X inactivation is effected by a large CIS-acting RNA molecule termed the X inactive specific transcript (XIST). Exon IV of XIST RNA is highly conserved at the primary sequence level and is predicted to form a stable stem-loop structure. These features suggest that it is important for XIST RNA function. We have used homologous recombination to delete exon IV(More)
