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 ...
Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

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, ...
Cas13 is capable of intrinsically targeting host RNA in mammalian cells through mechanisms that were not previously understood. Through transcript-specific mechanisms that are independent of the ...
For the first time, scientists have spotted rogue bits of RNA colonizing the bacteria in our gut. These “obelisks,” as the researchers have dubbed them, may represent a whole new class of infectious ...
