Scientists discover three meteorites contain all the building blocks of DNA

(ORDO NEWS) — Scientists have found that three meteorites contain the chemical building blocks of DNA and its companion RNA.

Some of these building blocks have already been previously found in meteorites, but the rest of the set has so far been missing from space rocks.

The new discovery supports the idea that four billion years ago, a meteorite bombardment could have provided the chemical elements needed to start the formation of the first life on Earth, the researchers say.
