Genetically modified organisms are potentially problematic because

• GMOs may be harmful to ecosystems

• GMO seeds or pollen can drift to organic farms

• farmers cannot reuse GMO seeds from past seasons

• all of these are negatives to the creation of GMOs

Stevia is a sweetener from plants in South America. Because of molecular analysis of the plant, two companies have been able to

• produce sweeteners molecularly similar to Stevia, but without the molecule that causes a bitter aftertaste.

• use gene editing to modify the plant so that it does not produce the molecule causing a bitter aftertaste.

• produce sweeteners molecularly similar to Stevia, but with fewer calories.

• use gene editing to increase the expression of genes that code for the molecules causing the sweetness of the plant.

Which of the following best describes a transgenic organism?

• It has had its genes altered through generations of selective breeding.

• It is the result of natural selection.

• It has had its genes mutated by exposure to radioactivity or chemicals.

• It contains DNA from another organism.
