These risks arise in a number of ways. Given the huge complexity of genetic coding, even in very simple organisms such as bacteria, no one can possibly predict the effects of introducing new genes into any plant. Therefore there is no way of knowing the overall, long-term effect on health. However, cross-species transfers being made between unrelated species, such as the transfer of modified agrobacterium genes, viral genes, and antibiotic resistant genes made in the proposed trials, would not happen in nature and may create new toxins, diseases, and weaknesses. In this risky experiment, the general public will be the ultimate guinea-pig.
Companies also claim their methods are precise.
In fact, there is a random element in all current gene insertion methods. Genetic research shows that many weaknesses in plants, animals and humans have their origin in tiny imperfections in the genetic code. Therefore, side-effects and accidents are inevitable, and some scientists have assessed the risks to be unlimited. Food Science Tech. The protein product of the transposed gene may carry out unexpected reactions and produce toxic products.
