* Insulin is a hormone naturally produced by the pancreas in humans and other animals. It's crucial for regulating blood sugar levels.
* Bacteria are single-celled organisms with a simpler genetic makeup than humans.
* Genetic engineering allows scientists to insert the gene for human insulin into the bacteria's DNA.
* Once the bacteria have the gene, they transcribe and translate the gene to produce insulin.
* This produced insulin is then extracted from the bacteria and purified for use as medication.
Why are bacteria used?
* Bacteria are relatively easy to grow in large quantities.
* Their reproduction cycle is fast, allowing for rapid insulin production.
* They can be genetically modified with relative ease.
So, the bacteria don't inherently "make" insulin, but they are *programmed* to do so through the process of genetic engineering. This allows for the production of large amounts of insulin for diabetic patients.
