How Sound is the Technology Behind GM Food?

HEALTH


GM technology is not precise or predictable. GM technology is a technique, which allows scientists to transfer genes into plants using a gene ‘construct’. Gene ‘constructs’ do not operate with precision, making the consequences of their use unpredictable. (See GM TECHNOLOGY AND GMO’S.) When scientists transfer ‘foreign’ genes into plants they cannot control how many of those genes will be taken up by the plant’s DNA, nor can they determine where on the plant’s DNA those ´foreign’ genes will insert themselves. What is more, in most cases the foreign genes cannot be appropriately controlled (switched on or off as needed) by the plant, and so remain active, or ‘switched on’ for the lifetime of the plant.

 

The GM transformation process can be disruptive.  GM technology transfers genes from one organism into another. This insertion of foreign genes into an organism can disrupt the organism’s natural gene function. Disturbance of plant host gene function can occur in a number of different ways. Firstly, the foreign gene can insert itself within host gene regions or their genetic switch-control elements, thereby disrupting their functions. Secondly, the GM-transformation process in general is known to introduce through as yet unknown mechanisms hundreds or even thousands of additional mutational defects in the DNA with potentially devastating consequences on the global host gene function.

The imprecision of GM technology raises questions about the genetic stability of GM plants and the safety of food (GM food), which is grown from them.
