Summarizing Recombinant DNA Technology















Using Biotechnology to
Produce Insulin

Insulin is normally produced by the __________________________. But in people who have
______________________, their pancreas can no longer produce the _______________________ insulin. Thankfully,
biotechnology has made it possible for
these folks to obtain large amounts of insulin in a safe way!
