2. Human insulinHuman insulin

Explanation:

Human insulin is made by genetically engineered microbes. They produce human insulin in a pure form. Human insulin is produced in a very controlled and clean environment. Genetically-engineered bacteria are grown in large stainless steel fermentation vessels. The vessel contains all the nutrients needed for growth. When the fermentation is complete, the mixture containing the bacteria is harvested. The bacteria are filtered off and broken open to release the insulin they have produced. It is then purified and packaged into bottles for distribution
