The flounder is a species of fish that can live in very cold water. the fish produces an "antifreeze" protein that prevents ice crystals from forming in its blood. the dna for this protein has been identified. an enzyme is used to cut and remove this section of flounder dna that is then spliced into the dna of a strawberry plant. as a result, the plant can now produce a protein that makes it more resistant to the damaging effects of frost. this process is known as
