How 3D DNA Architecture Shapes Cell Fate in Early Embryos

The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time.
