Question

Choose the incorrect statements:

I. Human insulin is made in fungus
II. Insulin DNA sequences are introduced into the genophore of E. coli
III. Recombinant E. coli produces insulin chains

• A. II, III
• B. I only
• C. III only
• D. I, II

Hint:

Insulin production involves plasmid vectors and recombinant {E. coli}, not fungi or genophores.

Answer 1

The Correct Option is D

- I: Incorrect — Human insulin is synthesized using genetically modified {E. coli}, not fungi.
- II: Incorrect — Insulin genes are introduced into plasmids, not directly into the genophore (main chromosome).
- III: Correct — Recombinant {E. coli} produces separate A and B chains of insulin which are then chemically joined.
