To review the structural and functional compartmentalization of macromolecular domains governing DNA replication, transcription, RNA processing, and nucleolar function within the eukaryotic nucleus.
Synthesized findings from autoradiography with [3H]-uridine incorporation and in situ nick translation to map transcriptionally active nuclear regions.
Evaluated spatial distributions of pre-mRNA splicing machinery, hnRNP proteins, and poly(A)+ RNA across cellular models including yeast and amphibian germinal vesicles.
Demonstrated that splicing factors compartmentalize into discrete nuclear speckles targeted by specific arginine/serine-rich (RS) protein domains.
Characterized the dynamic redistribution of splicing and transcription machinery driven by active RNA polymerase II transcription across distinct subnuclear compartments.
