Genes that code for a specific protein can be inserted into bacterial plasmids, and then the plasmids are used to transform cells. Many useful human proteins are now synthesized by these transgenic bacteria. Uses for the
synthesized proteins include human insulin used to treat diabetes and human growth hormone used to treat
dwarfism.
