Match the following.

 

	Column I		Column I
(a)	Primary structure	(i)	More than one polypeptide chains form structure and each chain as sub units of protein
(b)	Secondary structure	(ii)	Here helical polypeptide chain is further folded like a hollow woolen ball, it gives 3-D view. This structure is necessary for many biological activities of proteins
(c)	Tertiary structure	(iii)	Here polypeptide chains are folded in form of helix. Helix is only right handed
(d)	Quaternary structure	(iv)	It describes the sequence of amino acids i.e. position information in a protein
