How is bacteria used to make insulin?

Answer 1

Human plasmids introduced into the bacteria stimulate insulin production.

A special enzyme is used to cut out the insulin gene from a human cell. It is attached to a bacterial chromosome which is also split open by an enzyme. The gene is then transferred into a bacterial cell. The gene makes the bacterial cell produce insulin.

Answer 2

The ubiquitous bacteria E. coli can be genetically altered to produce insulin that is chemically identical to natural human insulin. Other organisms used to produce insulin include yeast (fungi).

Answer 3

Bacterial production of substances like human interferon, human insulin and human growth hormone can be made using simple bacteria like E. coli. These are manipulated to produce these chemicals so that they are easily harvested in vast quantities for use in medicine. Bacteria have also been modified to produce all sorts of other chemicals and enzymes.

Answer 4

Bacteria are genetically modified to produce human insulin by inserting the gene responsible for insulin production into their DNA. The bacteria then replicate and produce insulin, which can be harvested and purified for use in Diabetes treatment. This method is more cost-effective and has a higher yield compared to traditional methods using animal sources.

Answer 5

Bacteria, especially E. coli, can be used as vectors to produce human insulin. The insulin gene is inserted into a bacterium, which then produces insulin identical to what humans make.

Answer 6

Some bacteria contain plasmids. We can "clone" the gene that is responsible for insulin production into a plasmid thus making the bacterial cell produce insulin.

Answer 7

It is cheaper than processing pig pancreases. Bacterial fermentation can be easily scaled up, pork production cannot be.
