With regard to insulin choose correct options.

(a) C-peptide is not present in mature insulin.

(b) The insulin produced by rDNA technology has C-peptide.

(c) The pro-insulin has C-peptide.

(d) A-peptide and B-peptide of insulin are interconnected by disulphide bridges.

Choose the correct answer from the options given below.

1. (b) and (d) only

2. (b) and (c) only

Best answer

Answer: 3. (a), (c) and (d) only

Pro-insulin has chains A, B and a connecting C-peptide. During maturation C-peptide is removed, leaving A and B chains joined by disulphide bridges.

  • (a) true; (c) true; (d) true.
  • (b) false: rDNA insulin is made by producing A and B chains separately and joining them, so it has no C-peptide.

Correct: (a), (c) and (d) only.
