Replication-independent chromatin loading of Dnmt1 during G2 and M phases.

abstract：:Individuals affected by the autosomal recessive disorder Werner's syndrome (WS) develop many of the symptoms characteristic of premature ageing. Primary fibroblasts cultured from WS patients exhibit karyotypic abnormalities and a reduced replicative life span. The WRN gene encodes a 3'-5' DNA helicase, and is a member...
