초록/해제  
요약Eukaryotic cells compartmentalize intracellular components to segregate essential biological functions. While membrane-bound organelles have traditionally served this purpose, liquid-liquid phase separation (LLPS) emerges as a complementary mechanism in cellular spatial organization without membrane-bound structures. This dissertation investigates LLPS' roles in nucleus and genome organization by segregating functionally distinct nuclear compartments, each featuring a distinct set of biochemical reactions. We first discuss the development of CasDrop, a CRISPR/Cas9-based optogenetic tool, and how it can be used to study condensate-genome interactions. Specific focus is given to how transcriptionally active and inactive condensates can exclude each other, along with chromatin compartments enriched in active or inactive proteins. These chemical and mechanical effects can impact the local dynamics of the genome structure and its functional states. We further demonstrate that condensate surface tension can be harnessed to rapidly restructure genome organization. Finally, we reveal the complex, heterogenous organization within euchromatin; and probed its chromatin dynamics to investigate the correlation between transcriptional activity and chromatin dynamics at a genome-wide scale.
