ABSTRACT
Properly timed gene expression is essential for all aspects of organismal physiology. Despite significant progress, our understanding of the complex mechanisms governing the dynamics of gene regulation in response to internal and external signals remains incomplete. Over the past decade, advances in technologies like light and cryo-electron microscopy (Cryo-EM), cryo-electron tomography (Cryo-ET) and high-throughput sequencing have spurred new insights into traditional paradigms of gene expression. In this Review, we delve into recent concepts addressing ‘where’ and ‘when’ gene transcription and RNA splicing occur within cells, emphasizing the dynamic spatial and temporal organization of the cell nucleus.
