Why can we manufacture insulin for humans with bacteria?

Bacteria also carry equal number of Amino Acid. So, we can manufacture human insulin with bacteria

Explanation:

Human insulin is made in the lab inside with the help of common bacteria. Yeast is also used for making the insulin. The most common bacteria Escherichia coli is most common bacteria which is used for making insulin.

Researchers needs that human protein which is responsible for making bacteria. They make it through amino acid squeezing machine that is helpful for synthesizing the DNA. Manufacturers know exact order of insulin’s amino acid. There are twenty common amino acids which are helpful for making human insulin.  

d. organisms have cells with different shapes and functions.
