Human insulin on an industrial scale

Question

How can bacteria generate human insulin on an industrial scale? Describe the other forms of insulin made accessible by the pharmaceutical industry?

Answer 1

Bacteria do not naturally manufacture insulin. It is possible though to implant human genetic material comprising the insulin gene into bacterial DNA. The mutant bacteria then multiply and create human insulin. The insulin is isolated and purified for afterward commercialization. This biotechnology is termed as the recombinant DNA technology.

Besides human insulin, the pharmaceutical industry as well generates insulin to be employed by humans made up from the pancreas of cows and pigs.
