MCM2 promotes symmetric inheritance of modified histones during DNA replication

During genome replication, parental histones are recycled to newly replicated DNA with their posttranslational modifications (PTMs). It remains unknown whether sister chromatids inherit modified histones evenly. Here, we measured histone PTM partition to sister chromatids in embryonic stem cells. We found that parental histones H3-H4 segregate to both daughter DNA strands with a weak leading strand bias, skewing partition at topologically associating domain (TAD) borders and enhancers proxima…
