Question
Quaternary structure of protein
consists of four subunits
may be either or
is unrelated to two functions of the protein
is dictated by the primary structures of the individual subunits
Solution
D.
is dictated by the primary structures of the individual subunits
Proteins are linear polymers of amino acids. Many highly complex proteins consist of an aggregation of polypeptide chains, which are held together by hydrophobic interaction, and hydrogen, ionic bonds. Their precise arrangement constitutes the quaternary structure.
