Primordial Genetic Alphabet Enables Nonenzymatic RNA Replication

Swift Summary

• The Proceedings of the National Academy of Sciences (PNAS) published findings related to RNA copying chemistry in Volume 122, Issue 21, May 2025.
• Research addresses the challenge of biased incorporation of cytosine (C) and guanine (G) over adenine (A) and uracil (U), stemming from differences in base pair strength.
• Scientists hypothesized that substituting with 2-thiopyrimidine could help mitigate this bias.
