The Takeaway
Mutations that don't change the final protein product were long thought to be 'silent,' but they can actually change how mRNA molecules physically clump together. This reveals that RNA carries a second layer of information that dictates the physical texture and behavior of the cell's interior.
From the abstract
The capacity of mRNA to carry genetic information is long appreciated, but how the physical properties of RNA polymers impact function is less known. We developed a genetic algorithm that introduces synonymous mutations to control the heterogeneity of structures sampled by an mRNA. The behavior of the designed mRNAs indicates physical information can be embedded in the genetic code. We find that mRNA structural heterogeneity impacts RNA-RNA interactions and the physical properties of RNA-protein
