 This would be achieved using biotechnology methods to confer to them the capacity to alter nucleotides in the chromosomes of infected individuals through sequence-specific editing systems like CRISPR, ZFNs or TALENs.No known infectious agent naturally has the capacity to gene edit eukaryotes in a manner that can be flexibly targeted to specific sequences (distinct from substantially random natural processes like retroviral integration).By definition, HEGAA induced gene editing events are intended to occur outside of contained facilities such as laboratories or hospitals.
