Document Summary

Organism whose genetic material (dna) has been altered by scientists. Longer shelf life, more resistance to frost. Change the speed of growth, more fruits & veggies on trees. Growth time, size, insect resistance, protect against herbicides. Flavorful appearance / taste, increase nutrients, wider growing conditions. Pollen escapes to non-gmo farms or wild areas (genetic drift) Lack of genetic diversity and leaves crops vulnerable. Brazil nut genes have been inserted into some gmos soybean strains. Designed to resist pests, including the european corn and the western corn rootworm. U. s has no requirement that gmo foods be labeled. In europe, food containing gmo product has to be labeled. Cow & pig insulin was developed for human use production could not meet medical demand. Bioengineers began trying to create synthetic human insulin. 1982: humulin is the 1st genetically engineered medicine. Genes for human insulin inserted into e. coli. Bacteria multiply, pass on the human genes, produce large quantities of human insulin.
