Which is correct regarding genetically engineered insulin using E. coli?
  1. Difficult to purify
  2. Obtained in large unlimited quantities
  3. Possibility of transmission of animal diseases
  4. Insulin obtained varies in chemical structure
✓

Answer

  1. Obtained in large unlimited quantities
Explanation:

Human insulin is made by genetically engineered E. coli. They produce human insulin in a pure form that is less likely to cause allergic reactions. Human insulin is produced in a very controlled and clean environment. Genetically-engineered E. coli 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.
