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 ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

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 ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical ...

CRISPR-Cas13, a powerful RNA-targeting technology is gaining increasing attention as a next-generation gene therapy platform due to its precision and reduced side effects. Utilizing this system, ...

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 ...

By Hugo Francisco de Souza Emerging research suggests reversible RNA editing mechanisms may influence heart disease biology while opening new avenues for biomarkers and next-generation cardiovascular ...

RNA, or ribonucleic acid, is a short-lived molecule copied from DNA that enables cells to use genetic information. Specific DNA sequences are copied into RNA, which then delivers these instructions to ...
