Some of them: - Remove a key gene in a metabolic pathway which can be mitigated by dietary supplements, creating a biological dead man's switch in order to make it easier to control the population. - Inserting a viral genome into the host genome (preferably also under some deadman's switch), creating in effect a biological weapon
