how insulin is producedthrough genetic engineering is better than insulin isolated from animals,how was it genetically produced ?

The advantages of recombinant insulin over traditional insulin are:
(a) It is less expensive.
(b) It causes fewer allergic reactions.
(c) It is more rapidly absorbed and shows its effectiveness over shorter period of time.

Recombinant insulin was first prepared by Eli Lilly, an American company in 1983. They first prepared two DNA sequences corresponding to A and B chains of human insulin and introduced them in plasmids of E.coli to produce insulin chains. Chains A and B were produced separately, extracted and combined by creating disulfide bonds to form human insulin.
