protein chains display lifelike mobility in moving through a cell

Explanation:

One part of the cell theory as proposed by Mathias Scleiden, Rudolf Virchow and Theodor Schwann in 1830's states that: Cell is the fundamental and basic unit of life. This means that cell is the lowest form of any living thing that can be found.

However, in a case whereby protein chains display lifelike mobility in moving through a cell, this opposes the universal cell theory in the sense that protein molecule cannot display characteristics of life (movement) in a cell when the basic unit is CELL itself.
