Genetically engineered bacteria can be used to make muscle proteins and muscle cells. In medical use, that kind of bacteria can use to make the cloned muscle cells. That is created by using the patient's DNA. In that case, the patient's DNA will be separated from the muscle cells. Or any other wanted cell type). And then that DNA will be multiply by using PCR. After that DNA will transform into a virus that will be injected into the nucleus of bacteria. The own DNA must be terminated during that process. That thing can use to make muscle tissue for the patients, whose muscles are destroyed. But the same technology can use to make all other tissues. This kind of thing can use to make a large number of patients whose tissues are destroyed. But even if that technology is far away in the future artificial muscle cells can use to make food for people. Synthetic biology allows making the meat in cell cultures. That thing would give the solution for the ethics of meat p...
