Replication Timing Becomes Intertwined with 3D Genome Organization

摘要

Through dissecting the link between spatial genome organization and DNA replication timing, Sima et al. (2018) discover early replicating control elements (ERCEs), a new type of cis-acting elements that regulate replication timing, transcription, and multiple layers of three-dimensional features of genome organization. The study has important implications for unraveling control elements of high-order genome structure and function.
