Detailed explanation-1: -People with diabetes therefore have to inject insulin to control their blood sugar levels. Genetic engineering has been used to produce a type of insulin, very similar to our own, from yeast and bacteria? like E. coli?. This genetically modified insulin, ‘Humulin’ was licensed for human use in 1982.
Detailed explanation-2: -Humulin is the genetically engineered insulin produced by inserting human insulin gene into a host cell (E. coli) which was then allowed to grow and reproduce normally.
Detailed explanation-3: -Eli Lilly prepared the two DNA sequences complementary to the A chain and B chain of insulin. These DNA sequences were incorporated in the plasmids of E. coli. These two chains were synthesizes separately, extracted and combined by disulphide bonds to form genetically engineered human insulin.
