Some RNA molecules can create their own mirror images, suggesting similar molecules could have sparked life ROBERT F. SERVICE T oday RNA may seem over- shadowed by its glamorous cousin DNA, but many scientists think RNA molecules were the star play- ers in the origin of life. By both storing genetic information and copying them- selves, they might have touched off the march of evolution that produced increas- ingly complex life forms.
