# RNA as Structural Scaffold in Nuclear Organization

Specific RNAs build nuclear compartments, while a necessary pan-nuclear RNA mesh remains supported incompletely and requires a more selective material test.

Scope-matched aggregation gives Γ for the global meshwork (SC2/SC3). Specific RNA-dependent compartment nucleation retains Ζ under its local scope; it cannot carry the whole-interphase requirement. Strong positive RNA-protein structure studies prevent a purely associational dismissal, but no examined live global RNA-selective loss/rescue isolates necessary load-bearing material from the act of transcription or protein functions.

Local body formation, gene-rich compaction, heterochromatin stabilization or erosion, RNA-dependent enzymatic recruitment and mitotic eviction are separate measurable contexts. They are fixed by species, phase, compartment and molecular intervention before outcome, not by responders. None is automatically a pan-nuclear interphase necessity test.
