The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

Professor Zhou's research group focuses on developing and applying new technologies to visualize spatial and temporal distributions of chemical modifications in the mammalian transcriptome at ...

In an investigation to find out what sparked life on Earth, researchers have discovered that RNA formed through surprisingly ...

Proteins of all sizes and shapes do most of the work in living cells, and the DNA sequences in genes spell out the instructions for making those proteins. The crucial job of reading the genetic ...
