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 ...

The United States Food and Drug Administration has just approved the first-ever clinical trial that uses CRISPR-Cas13 RNA ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...

40,000-year-old RNA from permafrost-preserved tissue was recovered from a mammoth specimen known as Yuka. Molecular evidence from Yuka revealed a correction to the original assumption about Yuka’s sex ...

Scientists discover QT45, a self-replicating RNA molecule, offering insights into the origins of life on Earth.

“Our analyses show that the historical [human Rhinovirus] A genome represents an extinct lineage closely related to HRV A19 ...

A study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science ...

RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...
