RNA strand that nearly self-replicates could unlock life’s origin
A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...

RNA strand that can almost self-replicate may be key to life's origins
Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...
These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...
The discovery of catalytic RNA transformed our understanding of life's beginnings. Clare Sansom explores how the RNA world ...
