Biotechnology, industrial application of biological knowledge, in particular through the alteration of genes, called genetic engineering. Alteration of genes has been used to create new drugs, chemicals, and animal growth hormones, as well as therapies to repair genetic defects. Ethical and safety concerns about the uses of genetic engineering have generated many legal and moral conflicts in recent years.
