Bacteria are excellent candidates for genetic engineering because?

These prokaryotes, can be utilized for almost mass producing compatible human proteins, by placing a nucleotide sequence onto a plasmid, and placing it into the bacteria, letting the bacteria undergo reproduction, especially if the plasmid is integrated with the bacterial chromosome and undergoes transcription, more and more of the protein product can be made

Then can be extracted after lysing the cell, and using it for medical purposes for instance.
