A genetically engineered salmon (top) and a natural salmon of the same age (bottom). The ability to engineer and precisely edit the genomes of animals, while potentially beneficial, has raised ethical questions.

For instance, ongoing advances make it increasingly likely that scientists will someday be able to genetically engineer humans to possess certain desired traits. Of course, the possibility of human genetic engineering raises numerous ethical and legal questions. Although such questions rarely have clear and definite .

While scientific progress on molecular biology has a great potential to increase our understanding of nature and provide new medical tools, it should not be used as justification to turn the environment into a giant genetic experiment by commercial interests. Learn about the entire bioproduct life cycle from early-stage R to applied research including omics, biomarkers, as well as diagnostics, to bioprocessing and commercialization. Over the last years, the field of genetic engineering has developed rapidly due to the greater understanding of deoxyribonucleic acid (DNA) as the chemical double helix code from which genes are made.
