Question

Human insulin is being commercially produced from transgenic species of _____________.

• A. E. coli
• B. Brassica napus
• C. Bacillus thuringiensis
• D. Agrobacterium

Answer 1

The correct option is A E. coli

Human insulin is produced from genetically engineered E.coli. By using genetic engineering or recombinant DNA technology, insulin-producing genes from human beings have been transferred into E.coli. bacteria, which produced insulin called 'humulin' for clinical use. This type of insulin was produced commercially by an American pharmaceutical firm Eli Lily on 5th July, 1983.

So, the correct answer is 'E.coli'.
