Diabetics are unable to produce their own insulin and therefore must inject some into their body. Synthetic Insulin is created by bacteria using human coding.
The DNA sequence that contains the code for making __________ has been taken out of a human gene and placed into a single bacterium cell. The bacterium is cultivated in a fermenter, where it multiplies by copying and dividing itself.
The bacteria culture, that numbers millions simply follow the instructions in their genes and make the proteins that is encoded in the DNA.
