Question

Which of the following genetically engineered organisms was used by Eli Lilly to prepare human insulin?

• A. Yeast
• B. Virus
• C. Phage
• D. Bacterium

Hint:

Recombinant DNA technology, which involves inserting a gene into a host organism like bacteria, is a common method for producing important proteins like insulin.

Answer 1

The Correct Option is D

Eli Lilly utilized genetically modified bacteria, specifically \textit{Escherichia coli}, for the production of human insulin. This application of recombinant DNA technology involved the insertion of the human insulin gene into a bacterial plasmid, thereby facilitating the bacteria's production of the hormone. This was a pioneering use of genetic engineering in medicine.Consequently, the correct classification is Bacterium.
