Biotech supporters say the technique is precise and limited, so the resulting plants are no different except for the targeted changes (such as insect resistance). Now a thorough review of the scientific literature shows that biotech indeed works as intended. “Suspect unintended compositional effects that could be caused by genetic modification have not materialized,” the authors say.
