Genetic embryo editing
WebGenome editing is a way of making changes to specific parts of a genome. Scientists have been able to alter DNA since the 1970s, but in recent years, they have developed faster, cheaper, and more precise methods to add, remove, or change genes in living organisms. Researchers are working to develop therapies that use gene editing to treat children or … WebJul 26, 2016 · Though they found some enthusiasm among the public about gene editing, they also found that about two-thirds of U.S. adults have worries about the technology.
