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 ...
Important progress for RNA research: A team has discovered a new ribozyme that can label RNA molecules in living cells. RNA molecules are real all-rounders. They transfer the genetic information from ...

Self-building RNA strand may expose how life on Earth truly began
Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...
Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...
A study finds that an RNA enzyme, or ribozyme, can evolve to produce complex RNAs efficiently but at the cost of synthesis accuracy. Key to the development of RNA-based life, which is thought to have ...
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...
Atomic-resolution structure of a ribozyme yields insights into RNA catalysis and the origins of life
Which came first, nucleic acids or proteins? This question is molecular biology’s version of the “chicken-or-the-egg” riddle. Genes made of nucleic acids (DNA or RNA) contain the instructions for ...
In the March 19 Proceedings of the National Academy of Sciences, Mohammed Kashani-Sabet and colleagues describe the use of plasmid-based ribozymes as functional genomics tools to unravel complex ...
RNA molecules are real all-rounders. They transfer the genetic information from the DNA in the cell. They regulate the activity of genes. And some of them have a catalytic effect: just like enzymes, ...
