1 used to describe a living thing that has had the structure of its genes changed by scientists:
They produced genetically engineered crops resistant to herbicides.
Genetically engineered mouse models of mammary intraepithelial neoplasia.
Genetically engineered collagenase would presumably be possible, and this might overcome the batch-to-batch variability.
Recent examples of the organic movement's resistance against genetically engineered food29 point to a still critical position to the established agribusiness and food supply systems.
But even genetically engineered plants derive genes from their predecessors and need fertile soil in which to succeed.
The most important genetically engineered crops that have been introduced contained genes encoding insect resistance and herbicide tolerance; they were soybean, maize, cotton and canola.
To date, 50 food products containing genetically engineered organisms have undergone complete review.
These early studies highlight the strengths of studying gene function by using genetically engineered mice.
In 1999, about 40m hectares of genetically engineered crops were grown by a dozen countries, a 44 per cent increase on the previous year.
