The study suggests that some organic compounds associated with genetic material might have formed in a meteorite called Murchison before it landed in Australia in 1969. The chemicals are two kinds of nucleobases, ring-like carbon molecules that are essential for the creation of nucleic acids like DNA and RNA.
