Which of the following statement/s is/are wrong? I. Biotechnology deals with industrial scale production of biopharmaceuticals and biologicals using genetically modified microbes, fungi, plants and animals. II. Insulin consists of two short polypeptide chains: chain A and chain B, that are linked together by disulphide bridges. III. C peptide is not present in the mature insulin and is removed during maturation proinsulin into insulin. IV. The recombinant therapeutics induce unwanted immunological responses. V. For effective treatment of a disease, early diagnosis and understanding its pathophysiology is very important.

C-peptide of human insulin is (A) a part of mature insulin molecule (B) Responsible for formation of disulfide bridges (C) Removed during maturation of pro-insulin to insulin (D) Responsible for it biological activity

Correct the statement, if required, by changing the underlined word(s) The C-peptide is ul("added") during the maturation of pro-insulin to insulin.
