Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together. The discovery “opens up vast and ...
New modelling and single-cell analyses reveal how bacterial RNA repair shapes variable responses to ribosome-targeting ...
(PHILADELPHIA) -- The popular view is that DNA and genes control everything of importance in biology. The genome rules all of life, it is thought. Increasingly, however, scientists are realizing that ...
RNAs play an integral part in all kingdoms of life and mediate critical processes from gene regulation to genomic maintenance and protein synthesis. RNAs also have an amazing diversity in structure ...
Dr. Cech is a biochemist and the author of the forthcoming book “The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets,” from which this essay is adapted. From E=mc² to splitting the atom ...

🧬 This woolly mammoth enabled sequencing of 40,000-year-old RNA, a record!
The discovery of a juvenile woolly mammoth named Yuka, found in Siberian permafrost with its skin and muscles intact, has ...
The oldest RNA ever reported until now came from a 14,300-year-old “wolf” puppy frozen in permafrost. But when Mármol-Sánchez ...
In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved ...
- the template for protein synthesis; the form of RNA that carries information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell ...
