Question

Which of the following may decide characteristic of protein? A) Number of amino acids in the protein B) Number of disulphide bonds in the protein C) Number of polypeptide chains in the protein D) Sequence of amino acids in the protein

Answer 1

Answer is D, i.e. structural and functional characteristic of protein is decided by sequence of amino acids within it.

Explanation:

Linear chain of amino acids in a polypeptide determines the ultimate 3D folded structure it acquires as protein. In its 3D state, protein becomes ready to play its active functional role. Please read this answer as well.

Hence it is very important for a protein to possess right sequence of amino acids for becoming functionally viable.
