Answer:
protein chains display lifelike mobility in moving through a cell
Step-by-step explanation:
The cell theory as proposed by Mathias Scleiden, Theodor Schwann, and Rudolph Virchow in 1838 is a universally accepted theory that has three components which include; a) cell is the basic and fundamental unit of life b) All living organisms are composed of one or more cell c) Cells arise from pre-existing cells.
According to this question, the observation that "protein chains display lifelike mobility in moving through a cell" seem to contradict the cell theory because the CELL is regarded as the fundamental and basic unit of life, hence, it shouldn't contain any other living or moving molecule within itself.
