well Insulin is a hormone produced in the pancreas by the islets of Langerhans that regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.

jagr2713 · Answer

They take the gene for making insulin. Then they insert into bacteria by using DNA ligase then its inserted into the DNA . that is how recombinant dna is made. When the bacteria reproduce some will have the gene for insulin. The scientist will separate the bacteria with the gene and these will reproduce and have the gene for insulin. this site should help also http://www.nlm.nih.gov/exhibition/fromdnatobeer/exhibition-interactive/recombinant-DNA/recombinant-dna-technology-alternative.html

This works well in bacteria because many can easily use small circular "chunks" of DNA called plasmids.  Some species can literally find these plasmids in the environment and incorporate them into their cell.  It would be like us walking around and finding a new gene on the ground, sticking it into our cells, and start using it.
