A study of a bacteria commonly used in dairy fermentation revealed how organized RNA helixes, called riboswitches, can combine different signals to keep gene expression in check. Researchers from the ...

RNA transcription is the genomic process in which a cell produces a duplicate of a gene's DNA sequence. In a study published in Nucleic Acids Research, University of Alabama at Birmingham Department ...

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 ...

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 ...

Biologists have discovered that disruptions in transfer RNA function can lead to the development of cleft lip and cleft palate. Cleft lip and cleft palate are among the most common birth defects, ...

This work presents a redox-responsive strategy for precise RNA control via post-synthetic 2′-OH acylation. These introduced disulfide-containing acyl groups can be selectively cleaved upon exposure to ...

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.
