Some of the chemistry behind the genetic code may predate Earth itself. According to the video's description, certain compounds found inside 4.6-billion-year-old meteorites are thought to have originated in stars. The piece looks at how these ancient chemical traces may relate to the molecular building blocks of DNA.

• Chemical compounds found in 4.6-billion-year-old meteorites
• Possible link to the chemistry of the genetic code
• Compounds described as originating in stars, before Earth formed

Some of the chemistry that makes up our genetic code may have existed before Earth itself. Found inside 4.6-billion-year-old meteorites, these ancient compounds came from the stars…carrying chemical secrets that pre-date our planet.
