Step-by-step solution

The primary structure of a protein provides the positional information of amino acids in the polypeptide chain (A-III). The secondary structure involves local folding, and in proteins, only right-handed helices are observed (B-IV). The tertiary structure represents the overall three-dimensional folding of the protein chain upon itself, often described as being like a hollow woolen ball (C-I). The quaternary structure is the spatial arrangement of an assembly of more than one folded polypeptide or subunits with resp
