Insulin from pigs is cheaper and more readily available than insulin from humans.
the human insulin gene, which is located on the top of the short arm of chromosome 11 in human DNA, is cut from the DNA strand using restriction enzymes (genetics scissors). a plasmid (floating circular disks of DNA in bacteria) is extracted from a bacteria and cut open with another restriction enzyme, and the gene for human insulin is taken up by the plasmid. Another enzyme, ligase, is used to permanently seal the exposed nucleotides (ends of the DNA strands) together (like genetic glue). the plasmid is then put back into the bacterial cell, and the bacteria will then manufacture insulin. its offspring will also have the genetic data for human insulin.

The pancreas.
A transgenic organisms has one or more genes from another organism inserted into its genome.Transgenic bacteria with the gene for human insulin make human insulin that is used to treat people with Diabetes.

The boiling point of human insulin is 212 degrees Fahrenheit. When synthetic insulin is used, it must be kept in the refrigerator until use.
True in the 'manufacture' of Human Insulin - 'Humulin" genetically engineered bacteria are used to produce drugs and other chemicals that benefit humans.
Some diabetics claim that they get better control using insulin from cow or pig. The evidence is poor on support of the claim. Only one company in the world is licence to make insulin from animal extrict. Today 99% is made from 'human' DNA.

Yes, bacteria are used to make insulin. First restriction enzymes cut a human DNA strand where the gene to make insulin is located. Then, that fragment of human DNA is inserted into a bateria plasmid that reproduces and as it reproduces it creates more insulin.
the bacterial insulin is just human like insulin that cause no allergic reaction but earlier the insulin used was animal insulin
