Authored by Sabrina Lazar - Cell Biology and Professional Writing & 39;20Genetically Modified Organisms (GMOs): Engineered for GoodWhat if you could harness the power of mutations and induce them to give a specific amino acid change, giving the organism your desired phenotype? If you had enough of these organisms on a large enough scale, how could that affect a target population, or even the ecosystem?
