Genome editing is a technology that involves modifying DNA by cutting base sequences and joining them to other sequences. Genetic modification is a form of genome editing. More advanced methods are now emerging and are being commercialized in a variety of fields, including medical care and energy, not to mention foods. At the same time, precisely because the modification of genes has a direct impact on life, cautious discussion of safety and bioethics involving a broad swath of society is of paramount importance.
