About gene editing
Gene editing is an approach that allows scientists to make precise changes to a cell’s DNA. Several technologies allow scientists to cut DNA at specific spots, like scissors, so they can add, remove, or change genetic material where it is cut.
Gene editing can target somatic cells (any cell excluding egg and sperm cells) or germline cells (egg and sperm cells). Editing somatic cells only affects the individual treated, while germline edits may be passed to future generations. There are ethical considerations with germline editing as its impact can go beyond the person treated, and it is illegal in many countries.
