Folded protein structure of many polypetides is held and maintained by…………… .

(A) In natural rubber, the polyisoprene chains exist as coiled structure. (R) In polyisoprene Cis-configured chains are held together by weak Vander waals interactions.

Assertion : The long protein chain is folded upon itself like a hollow ball giving rise to the tertiary structure . Reason : Tertiary structure gives a 3-dimensional view of a protein.
