Some fundamental building blocks of our genetic code might have come from space

The building blocks of DNA and RNS have been found in a meteorite.

The Murchison meteorite fell on Australia in 1969 and in this meteorite have been found two types of nucleobases ring-like carbon molecules that are essential for the creation of nucleic acids.

It boosts the idea that the origin of life on Earth may have had an important contribution from an extraterrestrial object

This does not prove that nucleobases formed off earth as it is possible that the nucleobases are a result of earthy contamination but a comparison of ratio of carbon 13 to carbon 12 lead the team to conclude that the nucleobases formed off earth.

The sudie raises a very interesting question that was raised a very long time ago, but I don’t think it solves it

Organic compounds, including sugars and phosphates have been observed in interstellar dust and gas which raises the possibility that the molecules that life needed in order to form came from space.
