After we joined the delivery and the suppression systems, the whole scheme ended as shown in Figure 1. Plasmids containing TALEN/ZFN sites must be used to program organisms intended to be released into the environment. If any organisms shall be hacked, the first step would be to generate a bacteriophage solution in the laboratory. This solution will contain the bacteriophages at the required concentration, and the bacteriophages themselves will contain a phagemid with the appropriate TALEN/ZFN gene and the new program, if any. | After we joined the delivery and the suppression systems, the whole scheme ended as shown in Figure 1.

The Whole Scheme In order to be able to hack the genetic programming of a biological system, we need two main tools: i) a DNA delivery system and ii) a DNA suppression system. Both, the delivery and the supression systems should be very specific so that other organisms can not be damaged.
