The animations are relevant and eye catching and the information is at a level where students can understand the concepts being looked at
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.
All the equipment is kept sterile so that contamination cannot get into the medicine. Regular checks make sure that all the processes are working properly and the insulin meets the required quality.
Drag these processes into the correct order for making human insulin from genetically engineered bacteria.
