Refer to the Table Below, Which Shows Data Collected by a Research

Refer to the table below, which shows data collected by a research group investigating properties of a protein that catalyzes a chemical reaction in bacterial cells.The group isolated the protein from bacteria with normal function (native protein) and from three colonies of bacteria that had been treated with a chemical mutagen (mutants 1, 2, and 3) . Which statement is true and is supported by the results shown in the table?

A) The quaternary structure of a protein is destroyed by any change in its primary structure.
B) The tertiary structure of a protein is destroyed by any change in its primary structure.
C) Changes in primary structure can affect a protein's biological function without affecting its quaternary structure.
D) The same amino acids are responsible for determining a protein's biological function and its quaternary structure.
E) Any changes that disrupt a protein's quaternary structure cause disruptive changes in the protein's tertiary structure as well.
