Biotechnology—Genetic Engineering

Lecture no. 12 from the course: Understanding Genetics: DNA, Genes, and Their Real-World Applications

Biotechnology—Genetic Engineering

Taught by Professor David Sadava | 30 min | Categories: The Great Courses Plus Online Science Course

Insulin that treated individuals with diabetes, whose bodies don't create insulin (or enough of it) on their own, used to come from animals. Animal insulin, however, contains a different sequence of amino acids, so some people's bodies rejected it. The method of manufacturing insulin developed at a California hospital is how all insulin used to treat diabetics is now made.
