Abstract
Molecular motions take place within the cell. Considered in isolation these motions would have been impossible. It is only because they are coupled with chemical reactions within the cell that they can take place.
Keywords: Molecular motions within the cell, Tubulin, Microtubules, Actin, Dark bands, Light bands, Myosin, Treadmilling, Treadmill flow, Plus-end of a polymer, Minus-end of a polymer.
