As a result some patients were allergic to insulin sourced from animals and had damaging side effects as a result of treatment from these injections. The solution to this problem was solved by genetic engineering. The animation below shows how human insulin is produced by genetic engineering.

How Is Insulin Made Using Genetic Engineering? Insulin genes obtained from human cells are inserted into bacteria, which then produce the hormone, explains Dr. Erika Gebel of Diabetes Forecast for the American Diabetes Association.

Genetic engineering is the transfer of DNA from one organism to another using biotechnology. The organism receiving the DNA is said to be genetically modified (GM). Organisms are genetically ...

The insulin made in a person's body may become less effective if a phenomenon known as insulin resistance develops. Genetic and environmental factors interact to make insulin less effective at the ...

The Genetic Engineering of Insulin In the 1970s, scientists developed a way to produce human insulin, without using humans or animals. First, they genetically engineered pieces of DNA that coded ...

Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory ...

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. The genetic engineering process

en.wikipedia.org/wiki/Genetic_engineering

Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms .

Humulin is synthetic human insulin prepared by using genetic engineering. Humulin is manufactured from DNA sources in laboratory, using recombinant DNA technology. Synthetic insulin is also called genetically engineered insulin. The synthetic insulin (humulin) is as effective as hormone insulin secreted by human pancreas. Synthesis of Humulin

If the body does not produce any or enough insulin, people need to take a manufactured version of it. The major use of producing insulin is for diabetics who do not make enough or any insulin naturally. Before researchers discovered how to produce insulin, people who suffered from Type I diabetes had no chance for a healthy life.
