A recent news article says that the lander Philae on comet Churyumov-Gerasimenko 67P, has discovered a
rich array of organics
and it quotes one leading scientist as saying it is a
a frozen primordial soup
While "organics" don't necessarily mean life, (see related question What is meant by 'Organics' when discussing space exploration? ) it does offer the chance. On the other hand, DNA without life seems unlikely (there are some varied opinions on the matter)
Is Philae or any other space craft able to identify DNA?
Scope: past or current, spacecraft or lander.
