WebPhase separation of fluids is a physicochemical process by which molecules separate into a dense phase and a dilute phase. Phase-separated biomolecular condensates, which include the nucleolus, nuclear speckles, stress granules, and others, provide a mechanism to compartmentalize and concentrate biochemical reactions within cells ( 1 – 3 ). WebDec 1, 2024 · Phase separation and transcription. Transcription is a highly controlled process, wherein many different proteins must dynamically assemble at specific sites in the nucleus and act in concert to transcribe functionally relevant genes. Decades-long studies of eukaryotic transcription have shown that it involves a large number of proteins.
