The literature says it can sometimes recruit chromatin remodelers, but in my assays it seems to just sit in solution unless I use heavily digested chromatin.]]></description>

			<description><![CDATA[I’ve been trying to understand the specific role of the nucleolus in ribosome assembly for my cell biology project, but I keep hitting a wall. Every diagram and description makes it seem like a straightforward factory floor, yet I read that its structure and activity change dramatically depending on cellular stress and the cell cycle phase. My confusion is how this dynamic reorganization doesn’t completely disrupt the constant production of ribosomal subunits the cell needs.]]></description>

It got me wondering, how do we actually *know* it's still alive in that form, rather than just being a perfectly preserved structure? The line seems so fine when all metabolic activity appears to have stopped.]]></description>
