# Narration and storyboard draft: RNA as Structural Scaffold in Nuclear Organization

Authored draft, approximately 60–90 seconds; no rendered video claimed.

Some RNAs truly build nuclear structures. Removing the long NEAT1 transcript removes paraspeckles, and RNA-domain experiments reveal how a defined body assembles. The broader question is whether a pervasive RNA mesh is mechanically necessary to keep the whole interphase genome open. SAF-A rescue experiments, RNA-rich transcription pockets and rapid physical scaffold manipulations provide a substantial positive case. But each test changes more than RNA material alone: protein domains have several functions, RNA cleavage can terminate polymerase, and RNase digestion often uses permeabilized or extracted nuclei. Retained RNA abundance also differs from RNA still attached to a polymerase. Rapid molecular exchange does not automatically rule out a transient scaffold. Our Gamma rating therefore applies to the global necessity claim, while defined RNA-dependent compartment assembly receives Zeta. The next experiment needs selective, reversible RNA-material disruption in living interphase cells, independent mechanical measurements, and specific rescue while polymerase and protein state remain controlled.

1. Show the exact claim, grade and confidence.
2. Show selected publication milestones; label experimental systems and clinical endpoints.
3. Contrast the strongest result with its source-specific limitation.
4. End with the boundary experiment and primary-source links.
