Inside your body’s cells, molecules called DNA act as instruction booklets. DNA tells the cells within every living thing which molecules to make. Everything about you — your hair color, height, voice — is determined at least partly by your DNA.

DNA and its partner molecule, RNA, are the only molecules in nature known to carry genetic information. Now, in a new study, scientists have created artificial molecules that also store genetic instructions. These new molecules — called “XNA” — ar...
