Human Insulin Human Growth Hormone (HGH)
E. coli that contains the gene for human insulin is genetically engineered, transgenic, and a GMO. Bacteria have been engineered to produce chymotrypsin, make human insulin, produce enzymes that increase shelf life of bread, and to produce enzymes that improve the taste and clarity of beer.

Human Insulin, is a replica of the insulin found naturally in human beings. These are synthetically prepared. An insulin analogue however is an altered form of this human insulin, by addition,subsitution or substraction of one/or more amino acid chain/s. This is done to make insulin more safe and effective for human use.

Genetically engineered insulin may have fewer side effects than the insulin previously extracted from the pancreases of other animals. This is because genetic engineering inserts human genes such as the gene for insulin production into the DNA of bacteria. As a result, the bacteria that produces human insulin, when used by diabetics, should produce fewer side effects.
-Human insulin does not cost as much as pig/animal insulin -Human insulin does not result in allergic reactions, such of insulin of an animal.
Human insulin is made with bacteria through recombinant DNA. It introduces a copy of human insulin DNA to a host cell, which then produces human insulin.
The insulin that we engineer bacteria to make (E.colidoes not naturally make insulin) is identical to human insulin.
Diabetes insulin is found in all four subjects. However, recombinant bacteria are primarily used as a main source of insulin for diabetic subjects.
No . . . human insulin is made from pig insulin, quite often.
Insulin from pigs or cows can cause immune reactions in some people, or people may develop an allergy to the insulin over time and it will be ineffective. Human insulin is not immunogenic and so is preferred.
Humans, who are not diabetic, make the insulin they need within their own bodies.
