Safety and Technical Considerations with Embryo Editing

Question 1 of 2

1. Question
Which of the following potential safety risks is most realistic for embryo editing?
- 1. The CRISPR-Cas9 molecules could become permanently embedded in the cell and keep on editing new genes in future generations, in a runaway chain reaction.
- 2. The inability to precisely control the exact edit might lead to unintended consequences or unknown effects on the genome and individual.
- 3. The edited humans will be more susceptible to bacterial pathogens, since the CRISPR-Cas9 molecules derive from a bacterial immune system.
- 4. Editing embryos to confer HIV resistance might accidentally result in the embryos getting infected with HIV in the process.
