When, bacteria multiply, they can pass off their genes that can combat antibiotics to their offspring. The human beta-globin gene and a functional viral thymidine kinase gene in developing mice. The inclusion of two effectors independently expressed through a tightly regulated promoter enhances the functional capability of this approach by facilitating genetic manipulation of strains that harbor an immunity gene or other resistance mechanisms for one of the selected effectors and also prevents any single inactivating mutation that silences one effector from disabling the system.

The idea behind the cloning technique is that each of the cells in an individual contains the same set of genes and, under the right conditions, should be capable of directing the development of a new genetically identical copy of the original animal. Preliminary research has shown that it is possible to alleviate the symptoms of Parkinson's disease by transplanting fetal pig brain cells into a patient's brains.
