Question

Bacteria used to produce human insulin chains is:

• A. S. typhimurium
• B. E. coli
• C. A. tumefaciens
• D. B. thuringiensis

Hint:

Recombinant insulin produced by E. coli has revolutionized the management of diabetes, providing a synthetic source that reduces allergic reactions compared to animal-derived insulin.

Answer 1

The Correct Option is B

Identifying the bacterial host. Escherichia coli (E. coli) is extensively used in recombinant DNA technology due to its well-understood genetics, ease of culture, and ability to express foreign genes efficiently. This bacterium has been genetically engineered to synthesize human insulin by inserting the human insulin gene. This allows the production of insulin that is chemically identical to the naturally produced human hormone, which is essential for the metabolism of sugars in the body.
