Final answer:
Intermediate filaments do not contain a bound nucleotide and primarily serve a structural role in the cell.
Step-by-step explanation:
Filaments that may contain a bound nucleotide include all of the following EXCEPT intermediate filaments. Actin and myosin are proteins that interact with nucleotides like ATP during muscle contraction and cellular movement. Microtubules are components of the cytoskeleton that also interact with nucleotides, particularly through the protein tubulin, which polymerizes in the presence of GTP. The 9+2 array is a specific arrangement of microtubules found in cilia and flagella, which also utilizes nucleotides for their movement.
However, intermediate filaments, which are primarily composed of proteins like keratin, vimentin, and lamin, do not bind nucleotides and serve mainly structural roles in the cell, resisting tension and maintaining cell shape.
