After a protein is synthesized during translation, what further process or processes is/are needed for it to be fully functional?
A)No further processing beyond the linear arrangement of amino acids is required.
B)Although minimal function can occur in the linear form, the protein is more active when it undergoes mitosis.
C)The protein first twists into a secondary structure and then "folds" into a specific tertiary structure for activation and function.
D)The initial protein produced is a "preprotein" that requires a series of depolarizations by electrical impulses for conversion to an active protein.

Proteins are not in their final forms for active function when they are first synthesized and require posttranslational modification, the further processing of the newly translated primary protein structure into at least its secondary and tertiary structures to make it fully functional. Secondary protein structure is a twisting of the primary structure as a result of the interaction of amino acids located near each other. Tertiary structure is the folding of the linear structure and occurs as a result of remote amino acids interacting with each other. Folding often creates a "pocket" within the protein that becomes an "active site," able to interact with other structures or substances.
