Evolution seen in 'synthetic DNA'

Molecules called polymerases help to faithfully copy the genetic information stored in single strands of DNA

Researchers have succeeded in mimicking the chemistry of life in synthetic versions of DNA and RNA molecules.

The work shows that DNA and its chemical cousin RNA are not unique in their ability to encode information and to pass it on through heredity.

The work, reported in Science, is promising for future "synthetic biology" and biotechnology efforts.
