Question

In the bacterial synthesis of humulin, the plasmid containing the human insulin gene is introduced into _____

• A. Pneumococcus
• B. E.coli
• C. Bt
• D. None of these

Answer 1

The correct option is B E.coli

The synthesis of Humulin (Artifically produced human insulin) was achieved by inserting the gene into E. coli via vector transformation. The vector used here is a plasmid which would contain the human insulin gene without the region that encodes for the Peptide C. This way, the protein produced in E-coli would be the active insulin and not the inactive proinsulin.
