Name: Date: Student Exploration: Genetic Engineering Vocabulary: callus, exon, genetic engineering, genetically modified organism, genome, green fluorescent protein (GFP), herbicide, insecticide, intron, promoter, transcription, transformation Prior Knowledge Questions (Do these BEFORE using the Gizmo.) What are some things that can damage a farmer’s crops? Bad weather, bacteria, diseases, pests, birds, and rats. What can farmers do to protect their crops? Utilize insecticides and pesticides to keep insects from damaging their crops, keeping the farm area clean to prevent rat infestations, and regularly checking on their crops. Gizmo Warm-up Many farmers use chemical herbicides to kill weeds and insecticides to kill insects. Using genetic engineering, scientists have developed ways to resist harmful crop pests. In the Genetic Engineering Gizmo, you will use genetic engineering techniques to create genetically modified corn. Check that Task 1 is selected. The Gizmo shows petri dishes that contain different strains of bacteria (white dots) and caterpillars (Lepidoptera sp. larvae). In the first challenge, your goal is to find bacteria that produce toxins that kill the caterpillars. Click Play ( ). What do you observe? Some of the caterpillars that were killed might've left some bacteria. • Which strains of bacteria were able to kill Lepidoptera sp. larvae? 4, 5, 8, and 10. Were some more effective than others? Explain. Yes. The strength of the strains could depend on how much they've evolved to kill caterpillars, or how much resistance the caterpillars have built up against that specific strand. Some bacteria are able to produce a toxin that kills Lepidoptera sp. larvae. Find out which gene is responsible for this toxin in the next step.
