Recombinant DNA Made by inserting foreign DNA into Plasmids

Plasmids are tiny rings of DNA from bacteria

INSULIN An example of a medical advancement due to

genetic engineering

Human insulin is a hormone that helps your body use sugar, and keeps blood sugar levels from getting too high or too low

The gene for human insulin is inserted into plasmids

The transgenic bacteria containing these plasmids make human insulin

The human insulin can be harvested from the bacteria and used to treat people with diabetes
