1. Is it possible to put animal genes into crops to increase their protein? What would be the consequences of an insect eating crops with animal genes implanted in them?

GA: It is not necessary to use genetic modification to increase the protein content of a plant, this can be done using nitrogen fertiliser. Nitrogen is a major component of amino acids which are the building blocks for proteins. Referring to genes as plant or animal derived, however, is misleading. Genes are made up of segments of DNA, consisting of four chemical bases adenine, thymine, guanine and cytosine, which are shared by all organisms. Many genes are shared between plants and animals. Most genetic modification is done using synthetic genes, the important outcome is what proteins the genes code for. Any effects of a gene on insect feeding would depend on the function of the gene.

 

2. Could a severe allergic reaction to a novel type of pollen or protein occur in those not normally allergic?

GA: An allergic reaction could occur to a new type of crop regardless of what method has been used to breed the crop. Crops bred using genetic modification go through rigorous testing before being accepted for human or animal consumption.
