Detailed explanation-1: -Change in “primary structure” (linear amino acid chain) will cause change in all other higher “protein structural levels” (secondary, tertiary, and quaternarystructure) and thus, change protein function as well.

Detailed explanation-2: -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.

Detailed explanation-3: -The four levels of protein structure are primary, secondary, tertiary, and quaternary.

Detailed explanation-4: -Denaturation is described as the change in the structure and function of a protein. The process of altering the shape of a protein so that the purpose is lost is acknowledged as denaturation.

Detailed explanation-5: -Each protein has its own unique shape. If the temperature or pH of a protein’s environment is changed, or if it is exposed to chemicals, these interactions may be disrupted, causing the protein to lose its three-dimensional structure and turn back into an unstructured string of amino acids.
