How might scientists check to make sure their GMO works? 

SELECT ALL THAT APPLY

• Add a fluorescent (glowing) gene (with the gene of interest) to see if the final product glows
• Add another gene (with the gene of interest), like a resistance to herbicide gene, to test for its addition in the final product.
• Add pests to the final product to see if they live or die.
