Question
A bacterium called Bacillus thuringiensis contains a protein that can kill cotton ballworms and certain other kinds of caterpillars. A different bacterium called Agrobacterium tumefaciens has the ability to insert its genetic material into plants.
Scientists in the late twentieth century took a gene from Bacillus thuringiensis and inserted it into specimens of Agrobacterium tumefaciens. Genetic material from the Agrobacterium tumefaciens specimens was then inserted into cotton plants. The goal of these tests was to reduce caterpillar infestation in the cotton plants.
These tests are an example of
A.
genetic modification.
B.
creating purebred species.
C.
natural selection.
D.
meiotic cell division

These tests are an example of **A. genetic modification.**
This process involves altering the genetic material of an organism—in this case, inserting a gene from one bacterium into another bacterium and then into a plant—to achieve a desired trait, such as resistance to certain pests.
