No two proteins with different amino acid sequences (primary structure) have identical overall structure. The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function. This is why mutations that alter amino acid sequence can affect the function of a protein. Hence, the correct answer is option 1.
