Kind: research · Impact: low

## In brief

- A study led by Dr. Lluís Ribas de Pouplana, ICREA, examines how the genetic code's correspondence between nucleotide triplets and amino acids may have arisen.
- The work focuses on protein-building RNA molecules that may preserve remnants of an ancestral genetic code.
- The source reports the findings as possible remnants rather than a settled explanation of the code's origin.

## Why it matters

The origin of the genetic code is one of the major open questions in evolutionary biology, so evidence from RNA molecules that may preserve earlier stages of the code bears on how life's molecular machinery began.
