Europan DNA

Many scientists believe the most likely place to find extant life in the Solar System beyond Earth is inside Jupiter's moon, Europa.  A water ocean is thought to exist under the moon's ice shell, and that ocean could support life.

The technology needed to plumb that ocean is currently being developed.  One among many scientific instruments under development is a DNA sequencer.  If life is found inside Europa and can be sampled, the sequencer could tell us whether that life had the same DNA as Earthly life or another type entirely.  Either answer would be remarkable.
