The Overall Folding of a Single Protein Subunit is Called

Question

The overall folding of a single protein subunit is called:
A) primary structure
B) secondary structure
C) tertiary structure
D) quaternary structure
E) All of these

Accepted Answer

The overall folding of a single protein subunit is called the tertiary structure. The primary structure refers to the linear sequence of amino acids, the secondary structure refers to local folding patterns such as alpha helices and beta sheets, and the quaternary structure refers to the arrangement of multiple protein subunits into a larger complex. Therefore, only option C is the correct answer.
