Which structure is not a component of the cytoskeleton?

Explanation:
The cytoskeleton is a network of filamentous protein structures in the cytoplasm that gives the cell shape, enables movement, and provides tracks for intracellular transport. It consists of three main filament systems: microfilaments (actin filaments), microtubules, and intermediate filaments. The nucleus, on the other hand, is a separate organelle enclosed by the nuclear envelope that houses the cell’s genetic material. It is not a filament and does not form part of the cytoskeletal network, though it can interact with cytoskeletal elements for positioning and organization.
